The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0076] In the description of the present invention, "a plurality of" refers to more than two. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0077] In the description of the present invention, unless otherwise clearly defined, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0078] This application provides a door body assembly. The door body assembly provided by this application is applicable to refrigeration equipment, and the refrigeration equipment can be a refrigerator / freezer, a wine cabinet, etc.

[0079] Please refer to Figures 1 to 3 , in the embodiment of this application, the door body assembly 10 includes a door panel 100, a door liner 200, a first end cover 300, a second end cover 400, and two column parts 500.

[0080] The door panel 100 and the door liner 200 are opposite and spaced apart in a first direction, the first direction is parallel to the thickness direction of the door body assembly 10, the door panel 100 is used to form the appearance surface of the door body assembly 10, and the door panel 100 can be made of a glass plate or a metal plate; the door liner 200 forms the inner side surface of the door body assembly 10. When the door body assembly 10 is assembled to a refrigerator, the door liner 200 faces the inside of the refrigerator. The first end cover 300 is connected to the same end of the door panel 100 and the door liner 200, the second end cover 400 is connected to the same end of the other side of the door panel 100 and the door liner 200, the first end cover 300 and the second end cover 400 are oppositely arranged in a second direction, the second direction is parallel to the height direction of the door body assembly 10. It is easy to understand that when the door body assembly 10 is applied to a refrigerator, the height direction of the door body assembly 10 is the same as the height direction of the refrigerator.

[0081] The two column parts 500 are connected between the door panel 100 and the door liner 200, the two column parts 500 are oppositely arranged in a third direction, the third direction is perpendicular to the first direction and the second direction, the third direction is the width direction of the door body assembly 10, one end of each column part 500 is connected to the first end cover 300, and the other end is connected to the second end cover 400. Among them, the two column parts 500 can be integrally formed with the door panel 100. For example, the door body assembly 10 can include a door shell, and the door shell includes a door panel 100 and two column parts 500 integrally connected to both sides of the door panel 100, that is, the door panel 100 and the two column parts 500 are two parts of the door shell. At this time, the door shell is designed to be roughly in a "U" shape; of course, the two column parts 500 can also be separately connected to the door panel 100, that is, the two column parts 500 are two independent structural parts respectively. The column parts 500 in the drawings of this embodiment are shown by the latter as an example, and it should not be regarded as a limitation to this application.

[0082] An insulation cavity 101 is formed between the door panel 100, the door liner 200, the first end cover 300, the second end cover 400 and the two column parts 500. The insulation cavity 101 is filled with insulation material (not shown in the figure). For example, a foaming liquid can be injected into the insulation cavity 101, and a thermal insulation foam layer is formed by a foaming process. The thermal insulation foam layer plays a role of thermal insulation to prevent cold air leakage inside the refrigerator when the door body assembly 10 is used in the refrigerator.

[0083] The thickness of the refrigerator door is related to the overall structural design of the refrigerator. For built-in refrigerators, as refrigerators are integrated with cabinets or other furniture, the depth of the refrigerator needs to be designed according to the standard size of the cabinet, and the requirements for the thickness of the door are getting higher and higher. In the relevant technology, the thickness of the refrigerator door is still relatively thick. At present, the thickness of the outer part of the thin door body is as thin as 52mm, which is not conducive to the size control of the refrigerator in the depth direction. It is difficult to achieve the consistency of depth with furniture such as cabinets. In addition, the more the door protrudes from the outside of the refrigerator body, the easier it is to interfere with the cabinet or cabinet when the door is opened at a larger angle, affecting the door opening angle.

[0084] To solve the above problems, in the embodiment of the present application, each component of the door assembly 10 is thinned. Figure 3 As shown, the door panel 100 includes a first surface 110 facing away from the door liner 200, and the door liner 200 is provided with an embedded portion 210 on one side facing the door panel 100. The first wall panel 310 includes a first end surface 311 facing the second wall panel 320, and the second wall panel 320 includes a second end surface 321 facing away from the first wall panel 310. The distance between the first surface 110 and the second end surface 321 is D 1 , the distance between the first surface 110 and the first end surface 311 is a, the minimum distance between the first end surface 311 and the embedded portion 210 is p, and the maximum distance between the embedded portion 210 and the second end surface 321 is e, satisfying: D 1 =a+p+e, 44mm≤D 1 ≤47mm.

[0085] The distance D between the first surface 110 and the second end surface 321 1 , which is almost equal to the thickness of the external part of the door assembly 10, i.e., the part of the door assembly 10 located outside the refrigerator body. Specifically, the thickness of the external part of the door assembly 10 can be reduced by reducing at least one of the dimensions a, p, and e while ensuring that each component has a certain strength.

[0086] In the door assembly of the embodiment of the present invention, the distance between the first surface 110 and the second end surface 321 is D 1 , D 1=a+p+e, by reducing at least one of the dimensions a, p, and e, 44 mm ≤ D 1 ≤47mm, the thickness of the external part of the door assembly 10 is reduced. Compared with the refrigerator door in the related art, the thickness dimension is reduced by at least 5-8mm. Therefore, under the same refrigerator thickness dimension, the refrigerator using the door assembly 10 of the embodiment of the present invention can have a larger depth dimension of the cabinet, which is beneficial to the installation of internal functions and structural components. For built-in refrigerators, the thickness of the external part of the door assembly 10 is reduced, which is beneficial to ensure the consistency of the assembly of the built-in refrigerator and the cabinet; moreover, the thickness of the external part of the door assembly 10 is reduced, which reduces the amount of over-box during the door opening and closing process of the door assembly 10, and can reduce the side gap space required for loading into the cabinet. At the same time, the door assembly 10 is not easy to interfere with the cabinet or cabinet, so that the door assembly 10 can open a larger door opening angle.

[0087] In some embodiments, 6mm≤a≤8mm, 6.5mm≤e≤8.5mm. In the related art, the thickness dimension a of the door of a conventional refrigerator is greater than 10mm, and the thickness e of the embedded portion extending into the insulation layer is greater than 10.5mm. This embodiment effectively reduces the thickness of the door assembly 10 by making 6mm≤a≤8mm, 6.5mm≤e≤8.5mm.

[0088] Please refer to Figure 4 , for the dimension a, the thickness of the door panel 100 along the first direction is defined as g, the thickness of the first wall panel 310 along the first direction is defined as h, and the glue layer between the door panel 100 and the first wall panel 310 is defined as i, then a=g+h+i. In order to reduce the thickness of the door body assembly 10, the thickness g of the door panel 100 and the thickness h of the first wall panel can be adjusted according to the size of the door body assembly 10 and the different load-bearing capacity of the switch action. In some embodiments, the thickness g of the door panel 100 satisfies: 2.1mm≤g≤3.2m. For example, in one embodiment, g=3.2mm, i=0.9mm, a=g+h+i=3.2+2.9+0.9=7mm.

[0089] In one embodiment, please continue to refer to Figure 4The first end cover 300 further includes a third wall plate 330, a fourth wall plate 340 and a fifth wall plate 350 connected in sequence, the third wall plate 330 is connected to the first wall plate 310, the fifth wall plate 350 is connected to the second wall plate 320, the fourth wall plate 340 is located between the first wall plate 310 and the second wall plate 320, and is arranged opposite to the first wall plate 310 and the second wall plate 320, the first wall plate 310, the third wall plate 330 and the fourth wall plate 340 are enclosed to form a handle groove 300a, and the notch of the handle groove 300a faces the outside of the door body assembly 10. Among them, the distance from the end of the first end surface 311 close to the notch along the first direction to the fourth wall plate 340 is b, and the minimum distance between the fourth wall plate 340 and the embedded portion 210 along the first direction is d, which satisfies: 18mm≤b≤20mm, 8.5mm≤d≤10.5mm.

[0090] It should be noted that the surface passing through one end of the first end surface 311 close to the notch and parallel to the first direction is the reference surface. Of the two intersection lines where the reference surface intersects with the fourth wall plate 340, the distance along the first direction between the intersection line close to the first wall plate 310 and the edge line connecting the fourth wall plate 340 and the fifth wall plate 350 is defined as c, such as Figure 4 As shown, p=b+c+d, wherein the size of c changes with the size of b and d.

[0091] The distance b corresponds to the width of the handle groove 300a at the groove opening (along the first direction). By making the distance b satisfy 18mm≤b≤20mm, the width of the handle groove 300a is set as small as possible while ensuring that the user's finger can be inserted into the handle groove 300a to apply force, so that the thickness of the external part of the door body assembly 10 can be reduced. The distance d is almost equal to the minimum thickness of the thermal insulation foam layer on one side of the handle groove 300a along the first direction. By making the distance d satisfy 8.5mm≤d≤10.5mm, the thickness of the external part of the door body assembly 10 can be further reduced while ensuring that one side of the handle groove 300a has a certain thermal insulation thickness.

[0092] To facilitate the structural design and appearance of the door assembly 10, the thickness of the external part of the door assembly 10 is consistent at all locations. Figure 5 and Figure 6 The second end cover 400 includes a third end surface 401 away from the door panel 100 along the first direction, and the distance between the first surface 110 and the third end surface 401 is D 2 Each column portion 500 includes a connecting surface 531, the connecting surface 531 is connected to the door liner 200, and the distance between the first surface 110 and the connecting surface 531 is D 3 , satisfied: D 1 =D 2 =D 3 .

[0093] Specifically, the above D can be satisfied by reducing the width of the second end cover 400 along the first direction and reducing the width of the column portion 500 along the first direction. 1 =D 2 =D 3 Dimension chain relationship.

[0094] As the thickness of the door body assembly 10 decreases, the dimensions of the upper and lower end covers along the thickness direction of the door body assembly 10 need to be reduced accordingly. The reduction in material of the end covers will lead to a decrease in strength and a weakening of the deformation resistance. In order to prevent the door body assembly 10 from deforming after thinning, a reinforcing structure can be provided to strengthen the first end cover 300 and / or the second end cover 400.

[0095] In some embodiments, please refer to Figure 7 The door assembly 10 further includes a first reinforcement member 600, which is disposed in the heat preservation chamber 101 and connected to the first end cover 300. By connecting the first reinforcement member 600 to the first end cover 300, the first end cover 300 and the first reinforcement member 600 form a whole that realizes an increase in local wall thickness, which can enhance the anti-deformation capability and better withstand the load, that is, the first reinforcement member 600 can be provided to assist in enhancing the strength of the first end cover 300, especially when the first end cover 300 is large in the width direction of the door assembly 10, the first end cover 300 can be effectively prevented from being deformed, thereby preventing the door assembly 10 from being twisted and deformed as a whole. The first reinforcement member 600 can be made of metal, so that the first reinforcement member 600 itself has higher rigidity and strength, which is more conducive to preventing the first end cover 300 from being deformed.

[0096] Among them, the first reinforcement 600 is arranged in the insulation cavity 101, that is, the first reinforcement 600 is connected to the inner side of the first end cover 300, rather than connected to the outer side of the first end cover 300. The first reinforcement 600 will not be directly affected by the coldness of the refrigerator, and condensation on the first reinforcement 600 can be avoided.

[0097] It can be understood that in order to better prevent the first end cover 300 from being deformed, the first reinforcement member 600 can extend along the width direction of the door assembly 10 (ie, the third direction mentioned above).

[0098] In some embodiments, the first reinforcement member 600 may be connected to at least one of the first wall panel 310 , the second wall panel 320 , the third wall panel 330 , the fourth wall panel 340 and the fifth wall panel 350 to reduce the effect of the weakened strength caused by the above-mentioned size reduction.

[0099] In one embodiment, please refer to Figure 7 and Figure 8The fourth wall plate 340, the fifth wall plate 350 and the second wall plate 320 enclose a first groove 300b, the first groove 300b and the handle groove 300a are arranged along the first direction, and the first groove 300b is located on the side of the handle groove 300a close to the door liner 200. The first reinforcement member 600 is arranged in the first groove 300b, and the first reinforcement member 600 includes a first reinforcement plate 610, a second reinforcement plate 620 and a third reinforcement plate 630 connected in sequence, the first reinforcement plate 610 is attached to the fourth wall plate 340, the second reinforcement plate 620 is attached to the fifth wall plate 350, and the third reinforcement plate 630 is attached to the second wall plate 320. Then, the first reinforcement member 600 is designed to conform to the inner contour of the first groove 300b, so that the first reinforcement member 600 can be fully attached to the fourth wall plate 340, the fifth wall plate 350 and the second wall plate 320 under the extrusion force of foaming.

[0100] The first reinforcement member 600 is designed to be in an “n” shape. The multi-bend design makes the first reinforcement member 600 itself have a higher strength, which can well bear the external force applied to the first end cover 300 and effectively prevent the first end cover 300 from being deformed. The first reinforcement 600 is generally bent into the above-mentioned shape by a sheet metal bending process, and has a certain elasticity (an inherent property of the material) after bending. Before installation, the opening angle of the first reinforcement 600 is larger than the opening angle of the first groove 300b, that is, the opening angle between the first reinforcement plate 610 and the third reinforcement plate 630 is larger than the angle between the fourth wall plate 340 and the second wall plate 320. After the first reinforcement 600 is installed in the first groove 300b, it is tensioned based on elastic force, so that the first reinforcement plate 610 is tightly attached to the fourth wall plate 340, and the third reinforcement plate 630 is tightly attached to the second wall plate; moreover, in the subsequent foaming process of the door body assembly 10, the above-mentioned three reinforcement plates of the first reinforcement 600 are subjected to the extrusion force of foaming, and are further tightly attached to the above-mentioned three wall plates, so that the anti-deformation effect of the first reinforcement 600 can be fully exerted.

[0101] In one embodiment, please refer to Fig. 9 , a first folding edge 640 is provided at one end of the first reinforcing plate 610 away from the second reinforcing plate 620. When the width dimension of the door body assembly 10 is large, the length of the first reinforcing member 600 itself is also set to be long. By providing the first folding edge 640 at one end of the first reinforcing plate 610, the strength of the first reinforcing member 600 itself is enhanced, and the first reinforcing member 600 itself can be prevented from being deformed due to its excessive length. In order to prevent the first folding edge 640 from obstructing the foaming liquid from entering the lower space of the first reinforcing member 600, the first folding edge 640 is in contact with the side of the first reinforcing plate 610 facing the third reinforcing plate 630.

[0102] In another embodiment, please refer to Fig.10The end of the third reinforcing plate 630 away from the second reinforcing plate 620 is provided with a second folded edge 650, which can also enhance the strength of the first reinforcing member 600 and prevent the first reinforcing member 600 from being too long and deformed. Similarly, to prevent the second folded edge 650 from obstructing the entry of the foaming liquid, the second folded edge 650 is attached to the side of the second reinforcing plate 620 facing the first reinforcing plate 610.

[0103] In one embodiment, if Figure 7 As shown, the first end cover 300 is further provided with a first buckle 360, which is clamped to the side of the second reinforcing plate 620 away from the fifth wall plate 350, and the first buckle 360 ​​is configured as an elastic buckle. By providing the first buckle 360 ​​to be clamped with the first reinforcing member 600, the first reinforcing member 600 can be stably fixed to the first end cover 300 before foaming, so as to prevent the first reinforcing member 600 from being loosened and falling due to vibration during the transportation of the door body assembly 10.

[0104] In some embodiments, please refer to Fig.11 The door assembly 10 further includes a second reinforcement member 700, which is disposed in the heat preservation chamber 101 and connected to the second end cover 400. Similarly, by connecting the second reinforcement member 700 to the second end cover 400, the second end cover 400 and the second reinforcement member 700 form a whole that realizes an increase in local wall thickness, which can enhance the anti-deformation capability and better withstand the load, that is, the second reinforcement member 700 can be provided to assist in enhancing the strength of the second end cover 400, especially when the second end cover 400 is larger in the width direction of the door assembly 10, the second end cover 400 can be effectively prevented from being deformed, thereby preventing the door assembly 10 from being twisted and deformed as a whole. The second reinforcement member 700 can also be made of metal, so that the second reinforcement member 700 itself has higher rigidity and strength, which is more conducive to preventing the second end cover 400 from being deformed.

[0105] Likewise, the second reinforcement member 700 may extend along the width direction (ie, the third direction) of the door assembly 10 .

[0106] In one embodiment, please refer to Fig.11 and Fig.12 The second end cover 400 includes a sixth wall plate 410 and a support portion 420 connected to the sixth wall plate 410, and the support portion 420 is provided with a support surface 421 extending along the second direction. The second reinforcing member 700 includes a fourth reinforcing plate 710 and a fifth reinforcing plate 720 connected to the fourth reinforcing plate 710, the fourth reinforcing plate 710 is in contact with the sixth wall plate 410, and the fifth support plate is in contact with the support surface 421.

[0107] In one embodiment, the second reinforcement member 700 may further include a sixth reinforcement plate 730, which is connected to one end of the fifth reinforcement plate 720 away from the fourth reinforcement plate 710, and the sixth reinforcement plate 730 is arranged opposite to the fourth reinforcement plate 710. By providing the sixth reinforcement plate 730, the second reinforcement member 700 is roughly designed to be "C"-shaped, which can enhance the strength of the second reinforcement member 700 itself and prevent the second reinforcement member 700 itself from being too long and deformed.

[0108] To facilitate the foaming liquid to enter between the sixth reinforcing plate 730 and the fourth reinforcing plate 710 , the length of the sixth reinforcing plate 730 along the thickness direction (ie, the first direction) of the door body assembly 10 is smaller than the length of the fourth reinforcing plate 710 along the thickness direction of the door body assembly 10 .

[0109] In one embodiment, if Fig.11 As shown, the second end cover 400 is provided with a second buckle 430, and the second buckle 430 is clamped on the side of the fourth reinforcing plate 710 away from the sixth wall plate 410. By setting the second buckle 430 to clamp with the second reinforcing member 700, the second reinforcing member 700 can be firmly fixed on the second end cover 400 before foaming, preventing the second reinforcing member 700 from shifting.

[0110] As the thickness of the outer portion of the door assembly 10 is reduced, the thickness of the thermal insulation foam layer in the door assembly 10 can also be reduced. In this case, in order to ensure the thermal insulation effect, in one embodiment, please refer to Fig.13 The door panel 100 includes a second surface 120 facing the door liner 200, and the door assembly 10 further includes a vacuum insulation panel 900 (also called a VIP panel), which is connected to the second surface 120. In this embodiment, the vacuum insulation panel 900 is provided to form an internal insulation structure of the door assembly 10 together with the insulation foam layer. The vacuum insulation panel 900 has good insulation effect even at a relatively thin thickness. Through the combined effect of the vacuum insulation panel 900 and the insulation foam layer, the thickness of the external part of the door assembly 10 is reduced while still achieving good insulation.

[0111] Alternatively, as the thickness of the outer portion of the door assembly 10 is reduced, the thickness of the thermal insulation foam layer inside it may not be reduced. For example, the door liner 200 may be moved inward toward the interior of the refrigerator body 20 to make the thermal insulation foam layer thicker toward the interior of the refrigerator body 20. In some embodiments, please refer to Fig.14The refrigeration device includes a box body 20, and the door liner 200 includes a flat portion 220 and a raised portion 230 connected to the side edge of the flat portion 220, the raised portion 230 extends into the box body 20 and is arranged around the opening of the box body 20, the flat portion 220 is arranged opposite to the door panel 100 along the first direction, and the flat portion 220 is also located in the box body 20. In this way, by extending the flattened portion 220 into the box body 20, that is, the door liner 200 moves inward toward the inside of the box body 20, part of the thermal insulation foam layer of the door body assembly 10 also extends into the box body 20. In other words, this embodiment transfers the thickness of the thermal insulation foam layer that needs to be reduced due to the thinning of the door body assembly 10 to the inside of the box body 20, thereby achieving the thinning of the thickness of the external part of the door body assembly 10, but the thickness of the entire thermal insulation foam layer can still be maintained unchanged (relative to before the door body assembly 10 was thinned). In this way, this embodiment adopts the above-mentioned setting, so that when the thickness of the external part of the door body assembly 10 is thinned, good thermal insulation can also be achieved.

[0112] In one embodiment, if Fig.14 As shown, the flattening portion 220 includes a third surface 221 facing away from the door panel 100, the box body 20 includes a front end surface 21, and the distance between the third surface 221 and the front end surface 21 is H, which satisfies: 4mm≤H≤10mm. By extending the flattening portion 220 into the box body 20 for a greater distance, more thermal insulation foam layers of the door body assembly 10 are extended into the box body 20 without affecting the internal volume of the box body 20, so that the door body assembly 10 can be configured with a thermal insulation foam layer of sufficient thickness, thereby better improving the thermal insulation effect.

[0113] In one embodiment, the distance between the third surface 221 and the front end surface 21 is 6 mm.

[0114] Please refer to Fig.15 and Fig.16 Each column portion 500 includes a first side panel 510 and a second side panel 520 and a third side panel 530 connected to opposite ends of the first side panel 510, wherein the first side panel 510 forms a side wall of the door body assembly 10 along its width direction, the second side panel 520 and the third side panel 530 are relatively arranged along the thickness direction of the door body assembly 10, the second side panel 520 is connected to the door panel 100, and the third side panel 530 is connected to the door liner 200, and the first side panel 510, the second side panel 520 and the third side panel 530 enclose a "U"-shaped groove structure.

[0115] In one embodiment, a connecting portion (not marked) is protruded from one side of the first end cover 300 and the second end cover 400 toward the insulation chamber 101, and part of the connecting portion is inserted into the "U"-shaped groove, and the circumferential side surfaces of the connecting portion are respectively abutted against the first side plate 510, the second side plate 520 and the third side plate 530. Since the connecting portion is located between the second side plate 520 and the third side plate 530, the movement of the first end cover 300 and the second end cover 400 along the thickness direction of the door body assembly 10 can be restricted, thereby realizing the front and rear limiting of the column portion 500 and the upper and lower end covers.

[0116] In one embodiment, reference Fig.15 As shown, taking the connection between the first end cover 300 and the pillar part 500 as an example, a first limiting groove 300c is provided on the side of the connection part facing the door panel 100, and the pillar part 500 further includes a first limiting edge 521, which is connected to an end of the second side plate 520 away from the first side plate 510 and extends along the thickness direction of the door body assembly 10, and the first limiting edge 521 is plugged into the first limiting groove 300c. Through the plug-in cooperation between the first limiting edge 521 and the first limiting groove 300c, the first end cover 300 and the second end cover 400 are limited to move along the width direction of the door body assembly 10, and the left and right limiting of the pillar part 500 and the upper and lower end covers is achieved.

[0117] In one embodiment, please continue to refer to Fig.15 A second limiting groove 300d is provided on the side of the connecting portion of the first end cover 300 facing the door liner 200, and the column portion 500 may also include a second limiting edge 532, and the second limiting edge 532 is connected to an end of the third side panel 530 away from the first side panel 510, and the second limiting edge 532 is inserted into the second limiting groove 300d. Similarly, the cooperation between the second limiting edge 532 and the second limiting groove 300d can also limit the movement of the first end cover 300 and the second end cover 400 along the width direction of the door body assembly 10, further enhancing the left and right limiting of the column portion 500 and the upper and lower end covers.

[0118] In one embodiment, please refer to Fig.17 and Fig.18A third buckle 370 is provided on the circumferential side wall of the connecting part of the first end cover 300, and a fourth buckle 440 is provided on the circumferential side surface of the connecting part of the second end cover 400. The second side plate 520 and / or the third side plate 530 of the column part 500 are respectively provided with a first through hole 540 and a second through hole 550 at both ends along the height direction of the door body assembly 10. The first through hole 540 is arranged close to the first end cover 300, and the second through hole 550 is arranged close to the second end cover 400. The third buckle 370 is clamped in the first through hole 540, and the fourth buckle 440 is clamped in the second through hole 550. In this way, the first end cover 300 and the second end cover 400 are restricted from moving in the height direction of the door body assembly 10 through the cooperation between the buckle and the through hole, thereby realizing the upper and lower limit of the column part 500 and the first end cover 300 and the second end cover 400.

[0119] Thus, the above arrangement is adopted to achieve the limitation of the column part 500 and the first end cover 300 and the second end cover 400 in three directions, so that the two column parts 500 and the first end cover 300 and the second end cover 400 are connected reliably and firmly to prevent loosening.

[0120] It can be understood that the first end cover 300 bulges toward one side of the insulation cavity 101 to form a handle portion (the handle portion includes the above-mentioned first wall plate 310, third wall plate 330 and fourth wall plate 340), so less space is reserved for forming the insulation layer in the close-range area on the lower side of the first end cover 300, so that the thickness of the insulation layer close to the first end cover 300 is smaller than the thickness of the insulation layer in other parts. The coldness inside the refrigerator is likely to affect the first end cover 300, making the temperature of the first end cover 300 lower, and the handle groove 300a of the handle portion is connected to the external environment of the refrigerator. The moisture in the hot air outside the refrigerator condenses when it encounters cold, and condensation is likely to occur on the handle portion.

[0121] In this regard, in some embodiments, please refer to Fig.19 The door assembly 10 further includes a heat conducting member 800, which is disposed in the heat preservation chamber 101 and connects the door panel 100 and the first end cover 300. The heat conducting member 800 is made of a material with good thermal conductivity, and the heat conducting member 800 may be an aluminum plate.

[0122] By arranging a heat conductive member 800 in the heat preservation cavity 101 and connecting the heat conductive member 800 with the door panel 100 and the first end cover 300, the heat conductive member 800 plays a role in transferring heat, and can transfer the heat on the door panel 100 side to the first cover plate (the door panel 100 is far away from the door liner 200 and is directly affected by the external environment, and the temperature is relatively high), that is, the first cover plate exchanges heat with the door panel 100 through the heat conductive member 800, which can increase the temperature of the first cover plate, effectively reduce the impact of the refrigerator's coldness on the first end cover 300, and thereby reduce the condensation on the handle.

[0123] It is easy to understand that, since the fourth wall plate 340 is the wall plate where the handle is closest to the door liner 200, the fourth wall plate 340 is most affected by the coldness of the refrigerator, and condensation is most likely to occur on the handle mainly on the fourth wall plate 340. In one embodiment, the heat conducting member 800 includes a first heat conducting plate 810, a second heat conducting plate 820, and a third heat conducting plate 830, the first heat conducting plate 810 is attached to the fourth wall plate 340, the second heat conducting plate 820 is attached to the door plate 100, the third heat conducting plate 830 is connected between the first heat conducting plate 810 and the second heat conducting plate 820, and the third heat conducting plate 830 is spaced apart from the third wall plate 330.

[0124] As shown in the figure, through the above arrangement, the heat conducting member 800 is roughly designed to be in an inverted "Z" shape, and the first heat conducting plate 810 is attached to the fourth wall plate 340, the second heat conducting plate 820 is attached to the door plate 100, and the third heat conducting plate 830 is connected between the first heat conducting plate 810 and the second heat conducting plate 820, so that the heat on the side of the door plate 100 is transferred to the fourth wall plate 340 through the second heat conducting plate 820, the third heat conducting plate 830 and the first heat conducting plate 810 in sequence, thereby increasing the temperature of the fourth wall plate 340 and avoiding the fourth wall plate 340 from being heated. The plate 340 is overcooled, and in addition, the present embodiment arranges the third heat conducting plate 830 and the third wall plate 330 at intervals so that the heat on the door panel 100 side is directly transferred to the fourth wall plate 340 through the third heat conducting plate 830 and the first heat conducting plate 810, and will not be transferred to other parts of the handle part in the middle, so that the fourth wall plate 340 can fully exchange heat with the door panel 100 through the heat conducting member 800, thereby greatly reducing the influence of the coldness in the refrigerator on the fourth wall plate 340, and effectively preventing condensation on the fourth wall plate 340.

[0125] In order to space the third heat conducting plate 830 from the third wall plate 330, the first heat conducting plate 810 includes a first plate portion 811 and a second plate portion 812 connected to each other, the first plate portion 811 is attached to the fourth wall plate 340, and the second plate portion 812 is located outside the fourth wall plate 340 and connected to the third heat conducting plate 830. That is, a portion of the first heat conducting plate 810 is attached to the fourth wall plate 340, and a portion extends out of the fourth wall plate 340.

[0126] In some embodiments, please refer to Fig. 20 The heat conducting member 800 is provided with a liquid hole 840, and the liquid hole 840 penetrates the third heat conducting plate 830 and / or the second plate portion 812. The liquid hole 840 can be designed as a square hole, a round hole, an elliptical hole, etc., which is not limited in the embodiment of the present application.

[0127] It can be understood that, since the third heat conducting plate 830 and the third wall plate 330 are arranged at intervals, a cavity is formed between the third heat conducting plate 830, the second plate portion 812 and the third wall plate 330, which needs to be filled with foaming liquid for foaming and heat preservation. By providing the liquid-passing hole 840, the foaming liquid on one side of the heat conducting member 800 can enter the above-mentioned cavity through the liquid-passing hole 840, so as to form a heat-insulating layer between the third heat conducting plate 830 and the third wall plate 330. In order to allow the foaming liquid to fully and evenly fill the cavity between the third heat conducting plate 830 and the third wall plate 330, the number of the liquid-passing holes 840 can be set to multiple, and the multiple liquid-passing holes 840 can be arranged at intervals along the width direction of the door body assembly 10, that is, the third direction.

[0128] The liquid passage hole 840 may only penetrate the third heat conducting plate 830 , or only penetrate the second plate portion 812 , or penetrate both the third heat conducting plate 830 and the second plate portion 812 .

[0129] In one embodiment, if Fig. 20 As shown, the liquid hole 840 is disposed at the connection between the third heat conducting plate 830 and the second plate portion 812 , so that the liquid hole 840 passes through the third heat conducting plate 830 and the second plate portion 812 . During the foaming process, the foaming liquid generates an extrusion pressure on both the third heat conducting plate 830 and the second plate portion 812, so that the heat conducting member 800 is subjected to extrusion pressure in two directions, wherein the extrusion pressure of the foaming liquid on the third heat conducting plate 830 is along the second direction, and the extrusion pressure of the foaming liquid on the second plate portion 812 is along the first direction. In this embodiment, the foaming liquid is arranged at the connection between the third heat conducting plate 830 and the second plate portion 812, so that the foaming liquid on one side of the third heat conducting plate 830 can enter the cavity along the second direction, and the foaming liquid on one side of the second plate portion 812 can enter the cavity along the first direction, thereby reducing the extrusion pressure on the third heat conducting plate 830 and the second plate portion 812, that is, the extrusion pressure on the heat conducting member 800 in the above two different directions is reduced at the same time, and the risk of deformation of the heat conducting member 800 due to the extrusion effect of foaming is effectively reduced.

[0130] Among them, the heat conducting member 800 can extend along the width direction of the door body assembly 10, that is, the third direction, so that the first heat conducting plate 810 and the fourth wall plate 340 have a larger contact area, and the second heat conducting plate 820 and the door panel 100 have a larger contact area, so as to perform heat exchange at various locations of the fourth wall plate 340 and make the fourth wall plate 340 evenly heated.

[0131] In some embodiments, the first heat conducting plate 810 is spaced apart from the first side plate 510 of any pillar part 500 at any end along the third direction. And / or, the third heat conducting plate 830 is spaced apart from the first side plate 510 of any pillar part 500 at any end along the third direction. In this way, there are gaps between the two opposite ends of the first heat conducting plate 810 along the third direction and the first side plates 510 of the two pillar parts 500, and there are gaps between the two opposite ends of the third heat conducting plate 830 along the third direction and the first side plates 510 of the two pillar parts 500. The foaming liquid can enter from the opposite sides of the first heat conducting plate 810 and the third heat conducting plate 830 along the third direction, which is conducive to the foaming liquid flowing into the two diagonal parts of the door body assembly 10, so that the foaming liquid can fill the two diagonal parts of the door body assembly 10 well and fully.

[0132] In one embodiment, the width of the second side plate 520 of the pillar portion 500 along the third direction is the first width, and the distance between any end of the first heat conducting plate 810 along the third direction and the first side plate 510 of any pillar portion 500 is the first distance, and the first distance is greater than or equal to the first width. Similarly, the distance between any end of the third heat conducting plate 830 along the third direction and the first side plate 510 of any pillar portion 500 is the second distance, and the second distance is greater than the first width. In this way, a larger gap is left between the first heat conducting plate 810, the third heat conducting plate 830 and the first side plate 510, so that the foaming liquid can enter more easily, which is more conducive to the foaming liquid fully filling the diagonal part of the door body assembly 10.

[0133] In some embodiments, please refer to Fig.21 , the heat conducting member 800 further includes a third folded edge 850, the third folded edge 850 is connected to at least one end of the second heat conducting plate 820 along the third direction, and the third folded edge 850 is connected to the first side plate 510 of the column part 500. Referring to the figure, in one embodiment, the second heat conducting plate 820 is provided with third folded edges 850 at both ends opposite to each other along the third direction, and the two third folded edges 850 are respectively connected to the first side plates 510 of the two column parts 500.

[0134] In this way, by setting the third folded edge 850 at the end of the second heat conducting plate 820 along the third direction, the third folded edge 850 is connected to the first side plate 510 of the column part 500. On the one hand, the heat conduction area of ​​the heat conducting component 800 is increased, which can improve the heat conduction effect; on the other hand, the heat conducting component 800 is connected to the part of the column part 500 that is directly affected by the external environmental heat, so that the heat on one side of the column part 500 can also be transferred to the first wall plate 310 through the heat conducting component 800, thereby increasing the heat conduction path and further improving the heat conduction effect on the first wall plate 310.

[0135] The present application also provides a refrigeration device, which may be a refrigerator / freezer, a wine cabinet, etc. The refrigeration device includes a door assembly 10 conceived based on any of the above embodiments. Since the refrigeration device adopts all the technical solutions of the door assembly 10 of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments.

[0136] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
