[0047] In a double-door refrigerator, a flip beam is usually provided on one side of the refrigerator door body. After the two refrigerator door bodies are closed, the flip beam will rotate into the refrigerator inner liner for the relative ends of the two refrigerator door bodies to be sealed and covered. The refrigerator door body is generally adsorbed to the flip beam through a door seal to achieve the effect of isolating the refrigerator inner cavity from the external environment. However, the cold air in the refrigerator inner cavity is likely to exchange heat with the external environment through the door seal, resulting in a relatively large power consumption of the whole refrigerator.

[0048] Analyzing the above reasons, it can be known that the realization of the sealed adsorption between the refrigerator door seal and the flip beam is generally achieved by the magnetic attraction between the magnetic strip provided in the door seal and the armature on the flip beam. However, as a solid structure, the magnetic strip has a relatively high heat conduction efficiency, which is the main reason for the heat exchange between the cold air in the refrigerator inner cavity and the external environment.

[0049] In view of this, the present utility model provides a door seal structure, a door body structure and a refrigerator, aiming to improve the situation of heat exchange between the cold air in the refrigerator inner liner and the external environment through the door seal, and reduce the power consumption of the whole refrigerator.

[0050] Among them, Figure 1 is a schematic structural diagram of an embodiment of the refrigerator (partial structure) provided by the present utility model; Figure 2 is Figure 1 a partial enlarged view of A in Figure 3 is Figure 2 a schematic cross-sectional structure diagram of the door seal structure in Figure 4Schematic cross-sectional structure diagram when two door body structures of the refrigerator provided by the present utility model are closed.

[0051] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the door seal structure 11 is used for the refrigerator 1000. The refrigerator 1000 includes a turning beam 13 provided on the inner door liner 12 of the refrigerator. The door seal structure includes a main body portion 111. The main body portion 111 has a first side end 111a and a second side end 111b in its width direction. The first side end 111a is used to connect to the inner door liner 12. A magnetic strip pocket 1111 and a first airbag 1112 are formed in the main body portion 111. A magnet 113 is arranged in the magnetic strip pocket 1111. The first airbag 1112 is located at the second side end 111b and is adjacent to the magnetic strip pocket 1111.

[0052] Among them, forming the magnetic strip pocket 1111 in the main body portion 111 can be used for installing the magnet 113. At the same time, an armature 132 for adsorbing the magnet 113 is generally provided on the turning beam 13. The magnet 113 generally extends in the length direction of the main body portion 111, and its extension length is generally greater than the length of the armature 132 of the turning beam 13. The magnet 113 generally belongs to a solid structure and has a relatively high heat conduction efficiency. The external environment can easily directly contact the magnetic strip pocket 1111 through the second side end 111b of the main body portion 111 and may exchange heat with the magnet 113 therein.

[0053] The technical solution provided by the present utility model can ensure the natural adsorption strength between the door seal structure 11 and the armature 132 on the turning beam 13 through the setting of the magnetic strip pocket 1111 and the magnet 113 therein, achieving a sealing effect. Then, by arranging the first airbag 1112 adjacent to the magnetic strip pocket 1111 at the second side end 111b (the side end where the main body portion 111 contacts the external environment), through its own cavity structure property, the degree of cold air in the inner liner 21 of the refrigerator 1000 exchanging heat with the external environment through the main body portion 111 and the magnet 113 is reduced, and the overall power consumption of the refrigerator 1000 is reduced.

[0054] According to the analysis of the above embodiment, the way to slow down the heat exchange loss of the cold air in the inner liner 21 of the refrigerator should also include slowing down the heat exchange between the cold air in the inner liner 21 of the refrigerator and the magnet 113. In view of this, in some embodiments, a second airbag 1113 is formed in the main body portion 111. Along the width direction of the main body portion 111, the second airbag 1113 and the first airbag 1112 are located on opposite sides of the magnetic strip pocket 1111 and are both adjacent to the magnetic strip pocket 1111.

[0055] Among them, the second airbag 1113 functions similarly to the first airbag 1112, both including slowing down the heat exchange of the magnet 113. The difference is that the second airbag 1113 is located on the side of the magnetic strip bag 1111 close to the inner liner 21 of the box body. Therefore, the second airbag 1113 can prevent the cold air in the inner liner 21 of the box body from directly contacting the magnetic strip bag 1111, slowing down the heat exchange between the cold air and the magnet 113 therein. Combining with the first airbag 1112 slowing down the heat exchange between the external environment and the magnet 113, the heat exchange loss of the cold air in the inner liner 21 of the box body is further reduced.

[0056] Furthermore, please refer to Figure 3 , in some embodiments, the main body portion 111 has a third side end 111c and a fourth side end 111d in its thickness direction. The first airbag 1112 is formed at the third side end 111c; the main body portion 111 is further formed with a third airbag 1114 and a fourth airbag 1115. The third airbag 1114 is adjacent to the magnetic strip bag 1111 and is located at the fourth side end 111d, and the fourth airbag 1115 is adjacent to the second airbag 1113 and the fourth airbag 1115.

[0057] Among them, since the first airbag 1112 is formed at the third side end 111c, the third side end 111c can be understood as the end close to the flipping beam 13, that is, the end adsorbed to the flipping beam 13. The magnetic strip bag 1111 is usually also arranged at this third end. Combining with the first airbag 1112 being located at the second side end 111b defined in the above embodiment, it can be understood that the first airbag 1112 is located at the vertex position where the second side end 111b and the third side end 111c are adjacent; the fourth side end 111d can usually be understood as the end where the door seal structure 11 is connected to the inner liner 12 of the door body.

[0058] According to the above technical solution, through the arrangement of the third airbag 1114 and the fourth airbag 1115, the cavity structure in the main body portion 111 can be increased, thereby reducing the rigidity of the main body portion 111, enhancing its flexibility, and also enhancing the elasticity of the main body portion 111 in a timely manner. The magnet 113 is used in cooperation with the third airbag 1114 and the fourth airbag 1115. In actual use, the third airbag 1114 and the fourth airbag 1115 are stretched and deformed by the magnetic force, so that the local main body portion 111 corresponding to the magnetic strip bag 1111 is attracted to the armature 132 of the flipping beam 13, ensuring the sealing length of the door seal structure 11; not only that, since the fourth airbag 1115 is adjacent to the second airbag 1113, it can slow down the heat exchange between the cold air in the inner liner 21 of the box body and the second airbag 1113, that is, indirectly slow down the heat exchange between the magnet 113 and the cold air.

[0059] Of course, there are many other possible forms of setting the airbags in the main body portion 111, as long as they can play the role of enhancing elasticity and ensuring the sealing length. The embodiments of the present invention do not list them all.

[0060] Generally speaking, the sealing contact area between the door seal structure 11 and the turning beam 13 directly affects the ease of opening the door by the user. The larger the sealing contact area, the greater the opening resistance. In view of this, in some other embodiments, the magnetic strip pocket 1111 is formed at the first side end 111a; the main body portion 111 is provided with a reduced thickness on the side facing away from the first airbag 1112 of the magnetic strip pocket 1111, so as to form a stepped relief surface 118 corresponding to the reduced thickness of the main body portion 111 on the side end surface of the first side end 111a.

[0061] Among them, since the main body portion 111 is usually in an irregular shape, the first side end 111a and the second side end 111b are usually relative to each other. For example, please refer to Figure 3 , a small part of the main body portion 111 where the first airbag 1112 is formed belongs to the second side end 111b, and most of the rest in the width direction belong to the first side end 111a; "the main body portion 111 is provided with a reduced thickness on the side facing away from the first airbag 1112 of the magnetic strip pocket 1111" means that the dimension of the first side end 111a of the main body portion 111 in the thickness direction gradually decreases from the second side end 111b to the relative direction of the first side end 111a. Only in this way can a stepped relief surface 118 be formed on the side end surface of the first side end 111a. It can be understood that the side end surface of the magnetic strip pocket 1111 corresponding to the first side end 111a is at a higher position than the stepped relief surface 118 in the thickness direction, so that the magnetic strip pocket 1111 can first seal and contact the front surface of the turning beam 13 through the adsorption of the magnet 113 in the magnetic strip pocket 1111.

[0062] According to the above technical solution, a stepped relief surface 118 is formed on the side end surface of the first side end 111a of the main body portion 111. The stepped relief surface 118 does not directly participate in the sealing contact with the front surface of the turning beam 13. The side end surface corresponding to the magnetic strip pocket 1111 that is effectively adsorbed and contacted with the front surface of the turning beam 13 is higher than the stepped relief surface 118, so that the actual sealing contact area between the door seal structure 11 and the turning beam 13 is reduced. The reduction of the actual sealing contact area means that the opening resistance of the door body structure 100 is reduced, improving the user experience.

[0063] According to the above embodiment, the stepped relief surface 118 does not directly seal and contact the front surface of the turning beam 13, and the stepped relief surface 118 is adjacent to the magnetic strip pocket 1111. This results in that after the door body structure 100 is closed, the cold air in the inner liner 21 of the box may flow through the gap between the stepped relief surface 118 and the front surface of the turning beam 13 to the magnetic strip pocket 1111, so that it can exchange heat with the external environment through the solid magnet 113 provided therein. There is usually a problem of cold air loss. In view of this, please refer to Figure 3 and Figure 4, Further, in some embodiments, a first overlapping portion 114 is formed on the first side end 111a. The first overlapping portion 114 extends in a direction away from the second side end 111b. When it is used to overlap on the stepped end face 122 of the inner door liner 12, it can deform to make the stepped relief surface 118 bulge locally.

[0064] Among them, in the technical field of refrigeration equipment, a stepped structure is usually processed and formed on the door inner liner of the door body structure 100 of the refrigerator 1000. The stepped structure generally includes two stepped end faces 122 and a stepped side face 123 connecting the two stepped faces. The two stepped end faces 122 are arranged at different heights in the thickness direction of the door body structure 100. The lower stepped end face 122 is used to connect to the door body column 14 and is generally also used for the fixed installation of the door seal structure 11. The stepped end face 122 in this embodiment refers to the higher stepped end face 122; the first overlapping portion 114 in this embodiment is formed on the first side end 111a, and the stepped relief surface 118 is formed corresponding to the side end face of the first side end 111a. Therefore, the first overlapping portion 114 and the stepped relief surface 118 are adjacently arranged. The main body portion 111 of the door seal structure 11 is generally made of an elastic material. If the first overlapping portion 114 is stressed, it can change the shape of the stepped relief surface 118.

[0065] According to the above technical solution, since the first overlapping portion 114 extends in a direction away from the second side end 111b, after the door seal structure 11 is installed on the inner door liner 12 in this embodiment, the first overlapping portion 114 can abut against and overlap on the stepped end face 122 of the inner door liner 12. The first overlapping portion 114 immediately undergoes elastic deformation, so that the corresponding local area of the stepped relief surface 118 adjacent to it bulges toward the turning beam 13, and then it can block the gap between the stepped relief surface 118 and the turning beam 13 to prevent the cold air in the inner box liner 21 from flowing from between the stepped relief surface 118 and the turning beam 13 to the magnetic strip pocket 1111, playing a role in blocking the heat exchange between the cold air and the magnet 113 and blocking the leakage of cold air from between the magnet 113 and the turning beam 13;

[0066] Moreover, after the door seal structure 11 is installed on the inner door liner 12, the cold air in the inner box liner 21 may also leak from between the door seal structure 11 and the inner door liner 12. In this technical solution, by overlapping the first overlapping portion 114 on the stepped end face 122 of the inner door liner 12, the leakage path of the cold air can be blocked, thereby reducing the leakage of the cold air.

[0067] Furthermore, in some embodiments, a fifth airbag 1116 is formed in the main body portion 111 corresponding to the first overlapping portion 114 and the stepped relief surface 118.

[0068] By providing the fifth airbag 1116, a thin-walled structure can be formed in the main body portion 111, thereby reducing the rigidity of the main body portion 111 between the first overlapping portion 114 and the stepped relief surface 118 and enhancing its elastic deformation ability. This enables the first overlapping portion 114 to deform more easily when overlapping with the stepped end surface 122 of the inner door liner 12, making it easier for a local bulge to form on the stepped relief surface 118, and thus making it easier to block the gap between the stepped relief surface 118 and the turning beam 13.

[0069] In some other embodiments, the main body portion 111 has a third side end 111c and a fourth side end 111d in its thickness direction. The first airbag 1112 is formed at the third side end 111c; the first overlapping portion 114 is inclined towards the fourth side end 111d.

[0070] Among them, since the positions of the third side end 111c and the fourth side end 111d have been described in the above embodiments, they will not be elaborated in this embodiment; the first overlapping portion 114 being inclined towards the fourth side end 111d means that it is inclined towards the stepped end surface 122 inside the door. According to this technical solution, since the first overlapping portion 114 is inclined towards the stepped end surface 122 inside the door, during the installation of the door seal structure 11 onto the inner door liner 12, the first overlapping portion 114 of the door seal structure 11 can abut against the stepped end surface 122 perpendicularly, thereby directly generating a reaction force towards the turning beam 13, making it easier for the stepped relief surface 118 to deform and bulge.

[0071] Please refer to Figure 3 , in some embodiments, a second overlapping portion 115 is further formed at the first side end 111a. The second overlapping portion 115 extends in a direction away from the second side end 111b for overlapping with the stepped side surface 123 of the inner door liner 12.

[0072] Among them, the stepped structure of the inner door liner 12 has been described in the above embodiments and will not be elaborated in this embodiment. According to this technical solution, by providing the second overlapping portion 115, during the installation of the door seal structure 11 onto the inner door liner 12, the second overlapping portion 115 can be bent and deformed under the frictional action of the stepped side surface 123, thereby ensuring a lasting sealed overlap with the stepped side surface 123 and preventing the cold air in the inner box liner 21 from leaking out between the door seal structure 11 and the inner door liner 12.

[0073] Please refer to Figure 3 , in some embodiments, the main body portion 111 has a third side end 111c and a fourth side end 111d in its thickness direction. A magnetic strip pocket 1111 is formed inside the main body portion 111, and the magnetic strip pocket 1111 is formed at the third side end 111c; the second overlapping portion 115 is inclined towards the third side end 111c.

[0074] Among them, since the positions of the third side end 111c and the fourth side end 111d have been described in the above embodiments, they will not be elaborated in this embodiment. According to this technical solution, since the second overlapping portion 115 is inclined towards the third side end 111c, when the door seal structure 11 is installed into the door inner liner 12, the second overlapping portion 115 can deform along the relative movement direction with the step side surface 123, which can prevent the second overlapping portion 115 from being reversely folded relative to the step side surface 123 and causing sealing failure.

[0075] Please refer to Figure 3 , in some embodiments, the main body portion 111 has a third side end 111c and a fourth side end 111d in its thickness direction; a clamping portion 117 is formed at the fourth side end 111d, and the clamping portion 117 is used to be clamped to a clamping groove 121 provided on the door inner liner 12.

[0076] Among them, since the positions of the third side end 111c and the fourth side end 111d have been described in the above embodiments, they will not be elaborated in this embodiment; a clamping groove 121 is usually reserved on the door inner liner 12, and the clamping groove 121 corresponds to the position of the turning beam 13 and has the same extending direction. The clamping portion 117 in this embodiment is adaptively clamped to the clamping groove 121, playing a role in connecting the door seal structure 11 and the door inner liner 12.

[0077] Please refer to Figure 3 , in some embodiments, the main body portion 111 has a third overlapping portion 116 at the second side end 111b, and the third overlapping portion 116 extends away from the first airbag 1112 to overlap with the door body column 14 connected to the door inner liner 12.

[0078] Among them, the door body structure 100 of the refrigerator 1000 generally includes a door body column 14, and the door body column 14 is connected to the door inner liner 12, playing a role in supporting the door inner liner 12. The door body column 14 mentioned in this embodiment corresponds to the position of the turning beam 13. After the two door body structures 100 are closed, the door body columns 14 on them are arranged oppositely; after the door seal structure 11 is installed into the door inner liner 12, the cold air in the inner liner 21 of the box may leak to the door body column 14 through the gap between the door seal structure 11 and the door inner liner 12; the third overlapping portion 116 extends away from the first airbag 1112, that is, extends towards the door body column 14.

[0079] According to the above technical solution, after the door seal structure 11 is installed into the door inner liner 12, since the third overlapping portion 116 extends away from the first airbag 1112, the third overlapping portion 116 can closely overlap with the door body column 14, thereby blocking the gap between the door seal structure 11 and the door inner liner 12 and reducing the leakage of cold air.

[0080] The flip beam 13 needs to be rotated out of or into the inner liner 21 of the refrigerator along with the movement of the door structure 100 of the refrigerator 1000. It can be considered to seal the flip beam 13 and the inner liner 21 of the refrigerator from the outside. The original function of the door seal structure 11 is to eliminate the gap between the inner liner 12 of the door and the flip beam 13. It can be considered to provide a shielding structure on the door seal structure 11 to seal the flip beam 13 and the inner liner 21 of the refrigerator.

[0081] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the door seal structure 11 includes a shielding portion 112. The shielding portion 112 is formed by protruding from the second side end 111b of the main body portion 111 in a direction away from the first side end 111a, and is used to be placed on the inner liner of the refrigerator and the end of the flip beam.

[0082] Among them, in the prior art, the flip beam 13 usually needs to cooperate with a guiding structure to complete the flipping action. In this embodiment, the structure for realizing the flipping of the flip beam 13 is not limited thereto. For example, the flip beam 13 can also be flipped under the driving action of a driving motor provided on the inner liner 12 of the door. The inner liner 21 of the refrigerator mentioned in this embodiment includes any area or component opposite to the end of the flip beam 13; the width direction of the main body portion 111 generally refers to the direction opposite to another inner liner 12 after the door seal structure 11 is installed on the inner liner 12 of the door (when the two inner liners 12 of the door are closed). Since the first side end 111a of the main body portion 111 is used to connect to the inner liner 12 of the door, it can be understood that the second side end 111b of the main body portion 111 is the side end close to another inner liner 12, that is, the end on the outside of the door structure 100 relative to the inner liner 12 of the door; there are various possible connection methods between the first side end 111a and the inner liner 12 of the door, including fixed, detachable, and lapping, which are determined according to the specific structure of the first side end 111a of the main body portion 111. For example, when there are other side ends of the main body portion 111 for fixing to the inner liner 12 of the door, the first side end 111a does not have to be set as a fixed connection and can also be a lap joint. This embodiment does not limit this; the structural form of the shielding portion 112 can be a thin sheet structure or a thick structure, as long as it is ensured that the shielding portion 112 can be placed on the end of the flip beam 13 and the inner liner 21; the shielding portion 112 is formed by protruding from the second side end 111b of the main body portion 111 in a direction away from the first side end 111a, which means it extends towards another door liner structure.

[0083] It should be noted that the cross-section position in the attached Figure 3 drawing of the specification is at the middle of the length direction of the door seal structure 11. Therefore, the shielding portion 112 is not directly shown in the figure. In the actual product, the position of the shielding portion 112 is on the right side of the first airbag 1112.

[0084] The technical solution provided by the present utility model is to provide a shielding portion 112 on the main body portion 111 of the door seal structure 11. In a double-door refrigerator 1000 with a flipping beam 13, when the door body structure 100 equipped with the door seal structure 11 is closed, the shielding portion 112 will be in sealing contact with the flipping beam 13 along with the main body portion 111, and at the same time, it will overlap on the flipping beam 13 and the inner liner 21 of the refrigerator cabinet, thereby forming a shield between the flipping beam 13 and the inner liner 21 of the refrigerator cabinet, improving the situation where the cold air in the inner liner 21 of the refrigerator cabinet leaks out through the end of the flipping beam 13, reducing the power consumption of the whole machine, and also being able to improve the condensation situation on the surface of the flipping beam 13; the first airbag 1112 in this technical solution can not only play a role in delaying the heat exchange between the magnet 113 and the external environment, but also form a thin-wall structure at the corresponding position of the main body portion 111, which is conducive to the deformation of the shielding portion 112 as the magnet 113 adsorbs to the flipping beam 13, so as to adaptively overlap to the flipping beam 13 and the inner liner 21 of the refrigerator cabinet, which is conducive to improving the sealing effect of the shielding portion 112.

[0085] Generally speaking, the flipping beam 13 has two ends, and each end needs to be sealed with the inner liner 21 of the refrigerator cabinet. In view of this, please refer to Figure 3 In some embodiments, two shielding portions 112 are provided and are respectively arranged at both ends in the length direction of the main body portion 111 for overlapping on the two ends of the flipping beam 13 and the inner liner 21 of the refrigerator cabinet respectively. Among them, the length direction of the main body portion 111 usually corresponds to the length direction of the flipping beam 13, and the length dimension of the main body portion 111 is usually longer than the corresponding flipping beam 13, so that the two shielding portions 112 thereon can be aligned with the two ends of the flipping beam 13, and the two shielding portions 112 can respectively overlap on the two ends of the flipping beam 13 and the local areas of the corresponding two inner liners 21 of the refrigerator cabinet.

[0086] Please refer to Figure 2 and Figure 4 The present utility model also provides a door body structure 100, which includes a door inner liner 12 and a door seal structure 11, and the first side end 111a of the main body portion 111 is connected to the door inner liner 12. The specific structure of the door seal structure 11 refers to the above embodiments. Since this door body structure 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0087] In some embodiments, a flipping beam 13 is further provided on the door inner liner 12, and the flipping beam 13 is arranged to be flipped corresponding to the door inner liner 12.

[0088] It can be understood that the basic function of the flip beam 13 is to provide a sealed overlap between the door sealing structures 11 of the two door structures 100 so as to close the gap between the two door structures 100 when the two door structures 100 are closed. Therefore, it is not difficult to understand that the flipping method of the flip beam 13 is to flip along the axis of the length direction of the door sealing structure 11, which can also be understood as flipping along the axis of the height direction of the door structure 100. The position of the flip connection usually corresponds to the side end of the door sealing structure 11 set on the door body inner liner 12, which is not elaborated in this embodiment.

[0089] Since the door structure 100 in this embodiment is provided with a flip beam 13 , it also needs to cooperate with another door structure 100 that is not provided with a flip beam 13 to close the inner shell 21 of the refrigerator 1000 .

[0090] According to the working principle of the flip beam 13, whether the door body structure 100 is equipped with the flip beam 13 or not, the upper door sealing structure 11 has a relative flipping movement before sealing contact with the flip beam 13, which makes it easy for the flip beam 13 to have motion interference with the side of the door sealing structure 11 away from the shielding portion 112. The existence of motion interference is easy to generate motion resistance. Excessive motion interference is easy to cause aging and failure of the door sealing structure 11. In view of this, please refer to Figure 4 In some embodiments, a side of the flip beam 13 facing the door sealing structure 11 is provided with an avoidance step 131 .

[0091] It should be noted that the function of the avoidance step 131 is to avoid the side of the door sealing structure 11 on the two door body structures 100 that is away from the shielding portion 112, and this side of the door sealing structure 11 corresponds to the side end of the flip beam 13 in the width direction. Therefore, it can be understood that the avoidance step 131 is set one on each side of the flip beam 13 in the width direction.

[0092] In a specific embodiment, the flip beam 13 includes a flip shell, a cover and a lining iron 132 embedded in the flip shell; the door seal structure 11 has a magnet 113, the magnet 113 is adsorbed with the lining iron 132, and the avoidance step 131 is formed on the flip shell on the side of the width direction of the lining. The flip shell is an installation component and does not need to participate in the adsorption of the door seal structure 11. The part that is easy to interfere with the movement of the door seal structure 11 is on the flip shell. It is more reasonable to set the avoidance step 131 here, and the avoidance effect is good.

[0093] See also Figure 1 and Figure 2, in some embodiments, the present utility model further provides a refrigerator 1000. The refrigerator 1000 includes a door structure 100. The specific structure of the door structure 100 refers to the above embodiments. Since the refrigerator 1000 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the types of the refrigerator 1000 include but are not limited to double-door refrigerators.

[0094] In some embodiments, the refrigerator 1000 further includes a refrigerator main body 200. The refrigerator main body 200 has an inner box liner 21. Two door structures 100 are provided and are both rotatably arranged on the refrigerator main body 200. A turning beam 13 is rotatably arranged on the inner door liner 12 of one of the door structures 100. Among them, the two door structures 100 can jointly close the inner box liner 21 during their rotation strokes, and the main body parts 111 of the two door seal structures 100 can overlap the turning beam 13.

[0095] According to the above technical solution, the refrigerator 1000 obviously includes a double-door refrigerator. By providing the turning beam 13, it can significantly reduce the leakage of cold air in the inner box liner 21 through the gap between the two door structures 100. At the same time, a first airbag 1112 is provided in the door seal structure 11 on the door structure 100 and is arranged close to the outside, which can alleviate the problem of heat exchange loss of the cold air in the inner box liner 21 through the door seal structure 11 and the external environment.

[0096] The inner box liner 21 mentioned in the above embodiments belongs to a generalization concept, which includes a region opposite to the end of the turning beam 13 or components related to the turning beam 13. Specifically, please refer to Figure 2 , in some embodiments, the inner box liner 21 includes an inner liner body and a guide seat 211 provided on the inner liner body. The two ends of the main body part 111 of the door seal structure respectively extend to the corresponding regions of the inner liner body and the guide seat 211.

[0097] It should be noted that the turning beam 13 usually exists in the refrigerator 1000 together with the guide seat 211. When the inner door liner 12 provided with the turning beam 13 is closed, the mating part on the turning beam 13 will contact the guiding part on the guide seat 211, and thus, under the guiding action of the guiding part, it will change from the standing state relative to the inner door liner 12 to the flat state. The specific structure of the guide seat 211 is not limited in the embodiments of the present utility model.

[0098] Among them, since the turning beam 13 has two ends and only one end needs to be guided to complete the turning, in this embodiment, the guide seat 211 can be set as a single one corresponding to one end of the turning beam 13. For example, one can be set corresponding to the upper end of the turning beam 13, or one can be set corresponding to the lower end of the turning beam 13. At this time, the cold air in the inner liner 21 of the box may leak out between one end of the turning beam 13 and the guide seat 211, and between the other end of the turning beam 13 and the wall surface of the corresponding area of the inner liner body; the guide seat 211 can also be set one for each of the upper and lower ends of the turning beam 13. At this time, the cold air in the inner liner 21 of the box may leak out between the two guide seats 211 and the two ends of the turning beam 13. Since the existence of the turning beam 13 is not conducive to the pulling of the storage box body in the inner liner 21 of the box, the guide seat 211 is usually set as a single one corresponding to the upper end of the turning beam 13 only.

[0099] According to the above technical solution, since the two ends of the main body portion 111 respectively extend to the corresponding areas of the inner liner body and the guide seat 211, the main body portion 111 can play a role in shielding the two ends of the turning beam 13 from the corresponding areas of the inner liner body and the guide seat 211, thereby improving the situation that the cold air in the inner liner 21 of the box leaks out through the two ends of the turning beam 13, reducing the power consumption of the whole machine, and also being able to improve the condensation on the surface of the turning beam 13.

[0100] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
