[0008] The above technical solution has the following advantages or beneficial effects: by arranging the inner side of the connecting wall to extend outwardly towards a side away from the door front plate, and forming a sealing rib protruding towards the refrigeration compartment at the connection between the inner side of the connecting wall and the groove opening of the door seal groove, the distance between the sealing rib and the cabinet is reduced when the door body is closed in front of the refrigeration compartment, thereby reducing the thickness of the door seal clamped between the door body and the cabinet. Correspondingly, in the cooperation structure of the door seal and the sealing rib, a sealing groove is concavely provided at the connection between the outer side edge of the fixed portion and the gas bag portion away from the door front plate, the concave sealing groove can abut on the protruding surface of the sealing rib, not only tightly abutting the door seal and the connecting wall, but also reducing the thickness of the door seal. In this way, the thickness of the door seal can be reduced without changing the distance between the door body and the cabinet, and the protruding sealing rib towards the refrigeration compartment can also increase the foaming space formed between the door tank and the door shell, thereby filling more foaming material and having better thermal insulation performance.

[0009] In some embodiments of the present application, a refrigeration device is provided, and the connection between the connecting wall and the outer side edge of the groove opening is a circular arc transition, so that the surface of the sealing rib away from the door front plate side is a circular arc surface.

[0010] Another technical solution in the above technical solution has the following advantages or beneficial effects: by making the connection between the connecting wall and the outer side edge of the groove opening a circular arc transition, the contact area of the door seal with the connecting wall can be increased, thereby forming a more tight and uniform sealing contact surface, so that the sealing rib can tightly fit the sealing groove of the door seal in the compressed state. Moreover, during foaming, the connection between the connecting wall and the outer side edge of the groove opening is a circular arc transition, which is beneficial to the flow of the foaming material in the foaming space surrounded by the door liner and the door shell, improves the flowability of the foaming material, and avoids the problem of air bubbles caused by poor flowability of the foaming material.

[0011] In some embodiments of the present application, a refrigeration device is provided, and the connecting wall includes a first wall section, the inner side of the first wall section is connected with the outer side edge of the groove opening; in the direction from inside to outside, the first wall section extends outwardly and inclines towards the direction close to the door front plate; a second wall section is located on the outer side of the first wall section, and the inner side of the second wall section is connected with the outer side of the first wall section, and the outer side of the second wall section is connected with the door frame.

[0012] Another technical solution in the above technical solution has the following advantages or beneficial effects: when the door body is closed in front of the refrigeration compartment, the inner side of the first wall section extends towards the side of the refrigeration compartment, thereby reducing the distance from the end of the inner side of the first wall section to the edge of the box opening, thereby realizing the reduction of the door seal thickness while keeping the distance between the door body and the box unchanged. At the same time, due to the inclined extension of the first wall section, the available space between the door liner and the door shell is increased, providing a larger filling area for the foaming material, thereby improving the heat preservation performance of the door body.

[0013] In some embodiments of the present application, a refrigeration device is provided, and the connecting wall includes a first wall section, the inner side of the first wall section is connected with the outer side edge of the groove opening; in the direction from inside to outside, the first wall section extends outwardly and inclines towards the direction close to the door front plate; a second wall section is located on the outer side of the first wall section, and the inner side of the second wall section is connected with the outer side of the first wall section, and the outer side of the second wall section is connected with the door frame.

The first fin side extends from the outer end of the inclined wall to the side close to the door front plate.

[0018] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: when the door body is closed in front of the refrigeration compartment, the distance between the sealing rib and the box body is smaller than the outside, and the inclined wall is arranged on the inner side of the fixed part. The inclined direction of the inclined wall can be consistent with the connecting wall. The door seal can better cooperate with the sealing rib arranged in a convex manner. The thickness of the door seal on the side of the sealing rib is reduced. The door body, the door seal and the box body can better form a structure for cooperation and sealing. The heat preservation performance of the refrigerator is improved.

[0019] In some embodiments of the present application, a refrigeration device is provided. The connection between the inclined wall and the fixed part is a circular arc transition. The groove wall surface of the sealing groove abutting against the sealing rib is a circular arc surface.

The circular arc surface can cooperate with the surface of the sealing rib. The fit between the sealing groove and the sealing rib can be more uniform and more compact. Moreover, during repeated opening and closing of the refrigerator door, the sealing rib and the sealing groove will undergo slight deformation. The surfaces of the sealing rib and the sealing groove abutting against each other are both circular arc surfaces. The deformation can be effectively buffered. Material stress accumulation is reduced. Leakage problems caused by local fit problems are avoided.

[0021] In some embodiments of the present application, a refrigeration device is provided. The gas bag part includes a first gas bag arranged on the side of the fixed part away from the door front plate. A magnetic attraction part is arranged on the outer side of the first gas bag. A second gas bag is arranged on the outer side of the first gas bag. The second gas bag is arranged on the side of the magnetic attraction part close to the door body groove. A first partition wall is arranged between the first gas bag and the magnetic attraction part to separate the first gas bag and the magnetic attraction part.

On the inner side of the door liner, one side of the first air bag can directly abut against the cabinet, thereby achieving good sealing effect on the connection between the inner side of the door liner and the cabinet.

[0023] In some embodiments of the present application, a refrigeration device is provided, and the inclined wall is arranged on the side of the second air bag close to the connecting wall.

[0024] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: the inclined wall is arranged on the side of the second air bag facing the connecting wall, and the arrangement of the inclined wall makes the shape of the second air bag fit the sealing rib formed between the inner side edge of the connecting wall and the outer side edge of the groove opening. Moreover, due to the protruding arrangement of the sealing rib, the distance between the outer side of the door seal clamped between the cabinet and the door liner is reduced. By arranging an outer wall of the second air bag as an inclined wall, the cavity in the second air bag can be arranged to extend towards the side away from the door front plate, thereby reducing the thickness of the door seal at the position corresponding to the sealing rib, and making the outer side of the door seal better fit the structure of the sealing rib.

[0025] In some embodiments of the present application, a refrigeration device is provided, and the side of the second air bag away from the first air bag extends towards the outer side of the door liner and forms an extension cavity, at least part of the extension cavity is located on the outer side of the fixed part.

[0026] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: the extension cavity is arranged on the outer side of the sealing rib by the extension of the second air bag towards the outer side of the door liner. On the one hand, the extension cavity can compensate for the distance between the outer side of the connecting wall and the cabinet when the door is closed, and when the door seal abuts between the cabinet and the door liner, the gas in the second air bag can flow towards the extension cavity after being subjected to extrusion, thereby reducing the thickness at the relative position of the second air bag and the sealing rib, and the arrangement of the extension cavity provides additional elastic deformation space, which can achieve good sealing effect. On the other hand, the extension cavity is arranged on the outer side of the fixed part and on the outer side of the connecting wall, which can reduce the overall thickness of the door seal.

The sealing groove 204 is in abutment with the sealing rib 222.

[0083] It should be noted that the direction from inside to outside refers to the direction from the center of the door liner 22 to the outer peripheral edge of the door liner 22.

[0084] In the direction from inside to outside, the connecting wall 221 is arranged to extend outwardly and obliquely towards the direction close to the door front plate 211, that is, the inner side of the connecting wall 221 is arranged to protrude towards the side away from the door front plate 211, and a sealing rib 222 is formed between the inner side edge of the connecting wall 221 and the outer side edge of the slot opening 203 in a protruding manner. When the door body 2 is closed on the front side of the refrigeration compartment 101, the door seal 23 abuts between the door liner 22 and the cabinet 1. By arranging the inclined connecting wall 221 to form the sealing rib 222 protruding towards the side away from the refrigeration compartment 101, the thickness of the door seal 23 can be reduced, and the distance between the door liner 22 and the door shell 21 is increased, which provides more space for the foaming material. That is, the foaming space 201 enclosed by the door liner 22, the door frame 212 and the door front plate 211 is increased, and more foaming material can be filled. As a good thermal insulation material, the increase in the thickness of the foaming material can significantly improve the heat preservation performance of the door body 2.

[0085] As shown in some embodiments, the sealing groove 204 is recessed on the side away from the door front plate 211 at the connection between the outer side edge of the slot opening 203 and the air bag portion 231 of the fixed portion 232. The sealing groove 204 can be in abutment with the sealing rib 222. Figure 4 Figure 6 Figure 10 As shown in some embodiments, the sealing groove 204 is recessed on the side away from the door front plate 211 at the connection between the outer side edge of the slot opening 203 and the air bag portion 231 of the fixed portion 232. The sealing groove 204 can be in abutment with the sealing rib 222.

[0086] In some embodiments, a sealing groove 204 is recessed between the outer side edge of the slot opening 203 and the air bag portion 231 of the fixed portion 232, and the sealing groove 204 can match the protrusion of the sealing rib 222, so that the door seal 23 and the sealing rib 222 are in good cooperation at the protruding sealing rib 222, that is, the door seal 23 can be more closely fitted at the sealing rib 222. On the other hand, by recessing the sealing groove 204 between the outer side edge of the slot opening 203 and the air bag portion 231 of the fixed portion 232, the thickness of the air bag portion 231 corresponding to the abutting sealing rib 222 is reduced, the thickness of the door seal 23 is reduced, and the heat preservation performance of the refrigeration compartment 101 is improved. ​​

[0087] Currently, to improve the insulation performance of the refrigerator's cooling compartment 101, the main methods are to increase the thickness of the door liner 22 or decrease the thickness of the door seal 23. However, increasing the thickness of the door liner 22 or decreasing the thickness of the door seal 23 requires corresponding changes to the door hinge structure, typically necessitating adjustments to the hinge's dimensions. For mass production of refrigerators, this necessitates altering the mold for the door liner 22, the structure of the door hinges, and the structure of the door seal 23, requiring further investment in research and development and design efforts, and increasing manufacturing costs.

[0088] In this technical solution, by extending the inner side of the connecting wall 221 at an angle away from the front door panel 211, and forming a sealing rib 222 protruding towards the refrigeration compartment 101 at the connection between the inner side of the connecting wall 221 and the groove opening 203 of the door seal groove 202, the distance between the sealing rib 222 and the cabinet 1 when the door 2 is closed at the front of the refrigeration compartment 101 is reduced, thereby reducing the thickness of the door seal 23 sandwiched between the door 2 and the cabinet 1. Correspondingly, in terms of the mating structure between the door seal 23 and the sealing rib 222, a sealing groove 204 is recessed at the connection between the outer edge of the fixing part 232 and the airbag part 231, facing away from the front door panel 211. The recessed sealing groove 204 can be aligned and abutted against the protruding surface of the sealing rib 222, which not only makes the door seal 23 and the connecting wall 221 fit tightly together, but also reduces the thickness of the door seal 23. In this way, the thickness of the door seal 23 can be reduced without changing the distance between the door body 2 and the cabinet 1. Moreover, the sealing rib 222 protruding towards the refrigeration chamber 101 can increase the foaming space 201 formed between the door liner 22 and the door shell 21, thereby allowing more foaming material to be filled and achieving better thermal insulation performance.

[0089] like Figure 6 As shown, in some embodiments, the connection between the connecting wall 221 and the outer edge of the slot opening 203 is a rounded transition, so that the surface of the sealing rib 222 facing away from the front panel 211 is a rounded surface.

[0090] Wherein, since the inner side of the connecting wall 221 and the connecting part of the groove opening 203 of the door seal groove 202 form a sealing rib 222 which is arranged protruding towards the refrigeration compartment 101, the abutting of the door seal 23 on the sealing rib 222 is prone to wear or poor tightness. By transitioning the connecting part of the connecting wall 221 and the outer side edge of the groove opening 203 with a circular arc, the contact area of the door seal 23 and the connecting wall 221 can be increased, thereby forming a more tight and uniform sealing contact surface, so that the sealing rib 222 can tightly abut the sealing groove 204 of the door seal 23 in the compressed state. Compared with the current straight plane of the outer side edge of the groove opening 203, the door seal 23 can be better abutted with the door body 22 to effectively prevent cold air leakage. On the other hand, during foaming, the connecting part of the connecting wall 221 and the outer side edge of the groove opening 203 is transitioned with a circular arc, which is beneficial to the flow of the foaming material in the foaming space 201 surrounded by the door body 22 and the door shell 21, improves the flowability of the foaming material, and avoids the problem of air bubbles caused by poor flowability of the foaming material.

[0091] As shown in Figure 6 and Figure 10 in some embodiments, the connecting wall 221 includes a first section wall 2211. The inner side of the first section wall 2211 is connected to the outer side edge of the groove opening 203. In the direction from inside to outside, the first section wall 2211 extends outwardly and is arranged towards the direction close to the door front plate 211.

[0092] Wherein, the inner side of the first section wall 2211 is arranged close to the outer side of the groove opening 203, and the outer side of the first section wall 2211 is arranged close to the door frame 212. By connecting the first section wall 2211 with the outer side edge of the groove opening 203 and extending in an inclined manner, specifically, in the direction from inside to outside, the first section wall 2211 extends outwardly and is arranged towards the direction close to the door front plate 211, that is, the inner side of the first section wall 2211 extends in the direction away from the door front plate 211 relative to the outer side of the first section wall 2211, when the door body 2 is closed in front of the refrigeration compartment 101, the inner side of the first section wall 2211 extends towards one side of the refrigeration compartment 101, thereby reducing the distance from the end of the inner side of the first section wall 2211 to the opening edge of the cabinet 1, thereby realizing the reduction of the thickness of the door seal 23 while keeping the distance between the door body 2 and the cabinet 1 unchanged. At the same time, due to the inclined extension of the first section wall 2211, the available space between the door body 22 and the door shell 21 is increased, providing a larger filling area for the foaming material, thereby improving the heat preservation performance of the door body 2.

[0093] As shown in Figure 6 and Figure 10As shown, in some embodiments, the connecting wall 221 may include a second wall segment 2212. The second wall segment 2212 may be located outside the first wall segment 2211. The inner side of the second wall segment 2212 may be connected to the outer side of the first wall segment 2211, and the outer side of the second wall segment 2212 may be connected to the door frame 212.

[0094] The second section wall 2212 can be located at the peripheral edge of the door frame 22. The second section wall 2212 is located outside the first section wall 2211 and is directly connected to the door frame 212, thereby enhancing the connection strength between the door frame 22 and the door frame 212, so that the door body 2 can better disperse stress when subjected to external forces.

[0095] like Figure 6 As shown, in some embodiments, the second wall segment 2212 can be configured as an inclined wall surface. In the direction from the inside out, the second wall segment 2212 can be arranged to extend outwards at an angle closer to the front panel 211. The inclination direction of the second wall segment 2212 can be the same as that of the first wall segment 2211, and the inclination angle of the second wall segment 2212 is smaller than that of the first wall segment 2211, meaning the second wall segment 2212 is more gently sloping than the first wall segment 2211.

[0096] It should be noted that in some other embodiments, the second wall section 2212 can be configured as a plane. Specifically, the end of the door frame 212 away from the front panel 211 can be bent towards the side where the door core 22 is located to form a flange, and the outer side of the second wall section 2212 can be connected to the flange. The second wall section 2212 can extend along the plane where the flange is located.

[0097] Figure 6 In the diagram, M1 represents the first reference plane, and M2 represents the second reference plane.

[0098] like Figure 6 As shown, in some embodiments, the plane where the front panel 211 is located is the first reference plane, and the plane where the first section wall 2211 is located can be the second reference plane. The included angle α between the second reference plane and the first reference plane can be greater than 10°.

[0099] It should be noted that when the front panel 211 is curved, the plane on which the front panel 211 is located can also refer to the plane on which the front opening of the refrigeration compartment 101 is located.

[0100] By setting the included angle α to be greater than 10°, the thickness of the door seal 23, which abuts against the cabinet 1 and the door liner 22, can be reduced. If α is less than 10°, the inclination of the first section wall 2211 is insufficient, and the effect of increasing the foaming space 201 between the door liner 22 and the door shell 21 is not significant. At the same time, the thickness of the door seal 23 does not change much, and the effect of the door body 2 on improving the heat preservation performance of the refrigeration chamber 101 is not significant.

[0101] In some embodiments, the included angle a between the second reference surface and the first reference surface can be less than 60°. By setting the included angle a to be less than 60°, the foaming space 201 between the door liner 22 and the door shell 21 is increased, more foaming material can be filled, and the thickness of the door seal 23 is appropriate, thereby improving the heat insulation performance of the door body 2 and the overall heat preservation effect of the refrigerator.

[0102] In some embodiments, the included angle a between the second reference surface and the first reference surface satisfies 10° < a < 60°.

[0103] In the present embodiment, by setting the included angle between the plane where the door front plate 211 is located and the plane where the first section wall 2211 is located to be within 10°-60°, the inner side of the first section wall 2211 can be inclined towards the direction of the door front plate 211 in the closed state of the door body 2, so that the thickness of the door seal 23 abutting between the door liner 22 and the cabinet 1 is reduced. Since the sealing rib 222 is protrudingly arranged between the inner side edge of the connecting wall 221 and the outer side edge of the slot opening 203, the inclination angle of the connecting wall 221 will affect the insertion fitting position of the slot opening 203 and the door seal 23. Within the range of the included angle, it is beneficial to form a good fitting relationship between the door seal 23 and the door seal slot 202, so that the door seal 23 can be more closely fitted on the door liner 22 slot, effectively reducing the cold air leakage, and the thickness of the door seal 23 can be smaller while maintaining the size of the space between the door body 2 and the cabinet 1 unchanged, and achieving a better heat preservation effect.

[0104] As shown in Figure 8 and Figure 10 In some embodiments, the door seal 23 includes a first fin edge 233. The first fin edge 233 is arranged on one side of the air bag portion 231 close to the door frame 212 and abuts against the connecting wall 221. The first fin edge 233 is arranged on the outer peripheral side of the fixed portion 232.

[0105] In some embodiments, one end of the first fin edge 233 is connected to the outer side of the air bag portion 231, and the other end of the first fin edge 233 can extend towards one side of the door frame 212 and abut against the connecting wall 221. By arranging the first fin edge 233 on the air bag portion 231, the sealing contact area between the door seal 23 and the door liner 22 can be increased, and the first fin edge 233 can better fit the connecting wall 221, thereby improving the sealing effect and reducing cold air leakage.

[0106] As shown in Figure 8 and Figure 10As shown, in some embodiments, the first wing edge 233 extends obliquely. In the direction from the inside to the outside, the first wing edge 233 extends outward toward the front panel 211.

[0107] The inclined extension direction of the first wing 233 can be consistent with that of the connecting wall 221, allowing the first wing 233 to fit better against the connecting wall 221. Moreover, since the door seal 23 is generally made of silicone or other materials with a certain degree of elasticity, the inclined setting of the first wing 233 can fit against the connecting wall 221 and apply a certain rebound force, ensuring that the fixing part 232 of the door seal 23 is more firmly embedded in the door seal groove 202, reducing the risk of loosening or falling off due to long-term use.

[0108] like Figure 8 and Figure 10 As shown, in some embodiments, a sealing groove 204 is formed between the side of the first wing 233 facing the front panel 211 and the outer side of the fixing part 232.

[0109] Specifically, the outer side of the fixing part 232 refers to the outer side of the door sealing groove 202 corresponding to the fixing part 232. The sealing groove 204 is formed between the first wing 233 and the outer side of the fixing part 232. Since the inclination direction of the first wing 233 is consistent with the connecting wall 221, the sealing groove 204 can fit in a shape of a protruding sealing rib 222. This not only allows for better contact with the surface of the sealing rib 222, but also provides a buffering effect when the door 2 is closed, increasing the deformation force of the door seal 23 against the box 1 and the door liner 22.

[0110] like Figure 8 As shown, in some embodiments, an inclined wall 234 is provided on the outer side of the fixing part 232. The inclined wall 234 is disposed between the fixing part 232 and the first wing 233. In the direction from the inside to the outside, the inclined wall 234 extends outward at an incline toward the door panel 211. The inclined wall 234 can form a sealing groove 204 with the outer side of the fixing part 232. The first wing 233 can extend from the outer end of the inclined wall 234 toward the side of the door panel 211.

[0111] The inner side of the inclined wall 234 is connected to the outer side of the fixing part 232, and the outer shell of the inclined wall 234 is connected to the inner side of the first wing 233. A sealing groove 204 is formed between the inclined wall 234 and the outer side of the fixing part 232, so that the connecting wall 221 can abut against the inclined wall 234.

[0112] As the distance between the sealing rib 222 and the cabinet 1 is smaller when the door body 2 is closed in front of the refrigeration compartment 101, by providing the inclined wall 234 inclinedly arranged on the inner side of the fixed portion 232, the inclined direction of the inclined wall 234 can be consistent with the connecting wall 221, which not only enables the door seal 23 to better cooperate with the sealing rib 222 arranged protrudingly, but also reduces the thickness of the door seal 23 on the side of the sealing rib 222, so that the door tank 22, the door seal 23 and the cabinet 1 can better form a structure of cooperative sealing, thereby improving the heat preservation performance of the refrigerator.

[0113] As shown in Figure 8 some embodiments, the connection between the inclined wall 234 and the fixed portion 232 is a circular arc transition, so that the groove wall surface of the sealing groove 204 abutting against the sealing rib 222 is a circular arc surface.

[0114] Since the surface of the sealing rib 222 facing away from the door front plate 211 is a circular arc surface, by arranging the groove wall surface of the sealing groove 204 abutting against the sealing rib 222 as a circular arc surface, the circular arc surface can cooperate with the surface of the sealing rib 222, so that the fit between the sealing groove 204 and the sealing rib 222 can be more uniform and more compact. Moreover, during repeated opening and closing of the refrigerator door, slight deformation will occur between the sealing rib 222 and the sealing groove 204, and the surfaces of the sealing rib 222 and the sealing groove 204 abutting against each other are both circular arc surfaces, which can effectively buffer the deformation, thereby reducing the accumulation of material stress and avoiding the problem of cold leakage caused by local fit.

[0115] As shown in Figure 8 and Figure 10 in some embodiments, the air bag portion 231 includes a first air bag 2311. The first air bag 2311 is arranged on the side of the fixed portion 232 facing away from the door front plate 211. The first air bag 2311 is filled with gas. The first air bag 2311 is arranged on the side of the fixed portion 232 facing away from the door front plate 211, and when the door body 2 is closed in the refrigeration compartment 101, the first air bag 2311 can be clamped between the door tank 22 and the cabinet 1.

[0116] As shown in Figure 8 and Figure 10 in some embodiments, the air bag portion 231 includes a magnetic attraction portion 2312. The magnetic attraction portion 2312 is arranged on the outer side of the first air bag 2311.

[0117] Specifically, the magnetic attraction portion 2312 is arranged on the side of the first air bag 2311 away from the center of the door tank 22. The magnetic attraction portion 2312 can be provided with a magnetic attraction element, which can be magnetically connected with the cabinet 1. By providing the magnetic attraction portion 2312 in the air bag portion 231, the adsorption force between the door seal 23 and the cabinet 1 can be enhanced, and the sealing stability of the door seal 23 of the refrigerator is improved.

[0118] In some embodiments, the magnetic attraction member can be a magnet.

[0119] As shown in Figure 8 and Figure 9 In some embodiments, the air bag portion 231 includes a second air bag 2313. The second air bag 2313 is arranged outside the first air bag 2311. The second air bag 2313 is arranged on the side of the magnetic attraction portion 231 close to the groove of the door liner 22.

[0120] The second air bag 2313 can be filled with gas. Specifically, the second air bag 2313 is arranged on the side of the first air bag 2311 away from the center of the door liner 22, that is, the second air bag 2313 and the magnetic attraction portion 2312 are arranged on the same side, and the magnetic attraction portion 2312 is located on the end of the second air bag 2313 away from the fixed portion 232, so that the second air bag 2313 is located between the door liner 22 and the magnetic attraction portion 2312. In this way, when the door body 2 is closed in front of the cabinet 1, the door seal 23 is clamped between the door liner 22 and the cabinet 1, and the second air bag 2313 can be clamped between the magnetic attraction portion 2312 and the door liner 22. The second air bag 2313 can provide a closing door buffer force for the side of the magnetic attraction portion 2312 and the door body 2, while also serving as a sealing function.

[0121] As shown in Figure 8 and Figure 9 In some embodiments, the air bag portion 231 includes a first partition wall 2314. The first partition wall 2314 is arranged between the first air bag 2311 and the magnetic attraction portion 2312 to separate the first air bag 2311 and the magnetic attraction portion 2312. By arranging the first partition wall 2314, the first air bag 2311 and the magnetic attraction portion 2312 can form independent cavities.

[0122] As shown in Figure 8 and Figure 9 In some embodiments, the air bag portion 231 includes a second partition wall 2315 arranged between the first air bag 2311 and the second air bag 2313 to separate the first air bag 2311 and the second air bag 2313. One end of the second partition wall 2315 is connected to the first partition wall 2314, and the other end of the second partition wall 2315 is connected to the fixed portion 232.

[0123] The second partition wall 2315 has two ends along the thickness direction of the door seal 23. One end of the second partition wall 2315 is connected to the second partition wall 2315, and the other end of the second partition wall 2315 is connected to the fixed portion 232. The second partition wall 2315 and the first partition wall 2314 can divide the door seal 23 into the first air bag 2311 located on the inner side, and the second air bag 2313 and the magnetic attraction portion 2312 located on the outer side. The two sides of the second partition wall 2315 separate the first air bag 2311 and the second air bag 2313 to form independent cavities.

[0124] As shown in Figure 8 and Figure 9 In some embodiments, the air bag portion 231 includes a third partition wall 2316. The third partition wall 2316 is arranged between the second air bag 2313 and the magnetic attraction portion 2312 to separate the second air bag 2313 and the magnetic attraction portion 2312.

[0125] The third partition wall 2316 can separate the front and back of the portion of the door seal 23 close to the outer side. The magnetic attraction portion 2312 can be formed on the front side of the third partition wall 2316, and the second air bag 2313 can be formed on the back side of the third partition wall 2316, i.e., the magnetic attraction portion 2312 is arranged on the side of the second air bag 2313 away from the door liner 22.

[0126] Specifically, the first air bag 2311 is arranged on the side close to the inner side of the door liner 22, the second air bag 2313 and the magnetic attraction portion 2312 are arranged on the same side, and the magnetic attraction portion 2312 and the second air bag 2313 are arranged on the side close to the outer side of the door liner 22. When the door body 2 is closed in front of the refrigeration compartment 101, the first air bag 2311 can be clamped between the door liner 22 and the cabinet 1, the magnetic attraction portion 2312 and the second air bag 2313 can be clamped between the door liner 22 and the cabinet 1, and the second air bag 2313 can provide better deformation buffering capacity for the magnetic attraction connection between the magnetic attraction portion 2312 and the cabinet 1 on the outer side of the door liner 22, thereby achieving good sealing effect on the outer side of the door liner 22. On the inner side of the door liner 22, one side of the first air bag 2311 can be directly close to the cabinet 1, thereby achieving good sealing effect on the connection between the inner side of the door liner 22 and the cabinet 1.

[0127] As shown in Figure 8 and Figure 9 In some embodiments, the second partition wall 2315 is arranged to protrude towards the first air bag 2311, so that part of the second air bag 2313 can be arranged to extend towards the inner side of the door liner 22.

[0128] The second partition wall 2315 is arranged to protrude towards the first air bag 2311, so that a part of the second air bag 2313 is arranged to extend towards the inner side of the door barrel 22, and the second air bag 2313 extends towards the inner side of the first air bag 2311. When the door body 2 is closed on the front side of the refrigeration compartment 101, the compression of the first air bag 2311 can be transmitted to the first air bag 2311, so that the first air bag 2311 deforms correspondingly. Because the sealing rib 222 is arranged to protrude, the distance between the second air bag 2313 and the door seal 23 on the corresponding side is small, and the compression of the second air bag 2313 abutting between the sealing rib 222 and the cabinet 1 can also be transmitted to the first air bag 2311 correspondingly. In this way, the first air bag 2311 and the second air bag 2313 can cooperate with each other to more evenly disperse stress, and can better fill the gap between the door barrel 22 and the cabinet 1 when under compression, reduce cold air leakage, and improve the heat preservation performance of the refrigerator.

[0129] As shown in Figure 8 and Figure 9 In some embodiments, the second partition wall 2315 can include a first wall 23151 and a second wall 23152. One end of the first wall 23151 can be connected to the fixed part 232, the other end of the first wall 23151 can be connected to the second wall 23152, and the end of the second wall 23152 away from the first wall 23151 can be connected to the first partition rib.

[0130] As shown in Figure 8 and Figure 8 In some embodiments, the first wall 23151 can be arranged to extend obliquely towards one side of the first air bag 2311. The second wall 23152 can be arranged to extend obliquely towards one side of the second air bag 2313. In this way, the second partition wall 2315 can form a V-shaped structure. So that the door seal 23 can better fill the gap between the door barrel 22 and the cabinet 1 by the interaction of the first air bag 2311 and the second air bag 2313 when under compression.

[0131] As shown in Figure 9 In some embodiments, the inclined wall 234 can be arranged on one side of the second air bag 2313 close to the connecting wall 221.

[0132] Specifically, the inclined wall 234 is arranged on the side of the second air bag 2313 facing the connecting wall 221, and the arrangement of the inclined wall 234 makes the shape of the second air bag 2313 can fit the sealing rib 222 arranged in a convex manner between the inner side edge of the connecting wall 221 and the outer side edge of the slot opening 203. Moreover, since the sealing rib 222 is arranged in a convex manner reduces the distance between the outer side of the door seal 23 clamped between the cabinet 1 and the door barrel 22, by arranging an outer wall of the second air bag 2313 as the inclined wall 234, the cavity in the second air bag 2313 can be arranged to extend away from the side of the door front plate 211, thereby reducing the thickness of the door seal 23 corresponding to the sealing rib 222, so that the outer side of the door seal 23 can better adapt to the structure of the sealing rib 222.

[0133] As shown in Figure 8 and Figure 10 , in some embodiments, the side of the second air bag 2313 away from the first air bag 2311 is arranged to extend towards the outer side of the door barrel 22 and form an extension cavity 205. At least part of the extension cavity 205 can be located on the outer side of the fixed part 232.

[0134] It should be noted that the extension cavity 205 is part of the second air bag 2313, and the extension cavity 205 is in communication with the second air bag 2313.

[0135] Specifically, the extension cavity 205 is arranged to extend towards the outer side of the door barrel 22 by the second air bag 2313, so that the extension cavity 205 can be arranged on the outer side of the sealing rib 222. On the one hand, the extension cavity 205 can compensate for the distance between the outer side of the connecting wall 221 and the cabinet 1 when the door is closed, and when the door seal 23 is abutted between the cabinet 1 and the door barrel 22, the gas in the second air bag 2313 can flow towards the extension cavity 205 respectively after being extruded, thereby reducing the thickness of the second air bag 2313 at the relative position of the sealing rib 222, and the arrangement of the extension cavity 205 provides additional elastic deformation space, which can achieve good sealing effect. On the other hand, the extension cavity 205 is arranged on the outer side of the fixed part 232 and on the outer side of the connecting wall 221, which can reduce the overall thickness of the door seal 23.

[0136] As shown in Figure 8 and Figure 10 , in some embodiments, the air bag part 231 can include a second fin edge 235. The second fin edge 235 is arranged on the side of the first air bag 2311 facing the door barrel 22. The second fin edge 235 can be arranged to extend along the wall surface of the door barrel 22. The second fin edge 235 is arranged in a spaced manner between the outer side of the first air bag 2311 to form a buffer gap 206.

[0137] The second wing edge 235 is spaced apart from the outer side of the first air bag 2311 to form a buffer gap 206. When the door seal 23 is subjected to the extrusion force between the door body 2 and the cabinet 1, the buffer gap 206 can play a buffering role and provide a better elastic deformation space for the door seal 23. At the same time, the existence of the buffer gap 206 can absorb part of the external force impact during opening and closing of the door, and reduce the decline of the sealing performance of the door seal 23 due to fatigue damage in the long-term use process.

[0138] As shown in ​ and ​ In some embodiments, the air bag part 231 can include a third wing edge 236. The third wing edge 236 can be arranged on the inner side of the door seal 23. The third wing edge 236 can be arranged on the side of the first air bag 2311 towards the center of the door tank 22. The third wing edge 236 can abut on the side of the door tank 22 away from the sealing rib 222.

[0139] The third wing edge 236 can be attached to the wall surface of the door tank 22. When the door seal 23 is subjected to extrusion, the third wing part can play a certain supporting role, distribute the stress on the inner side of the door seal 23, so that the door seal 23 can deform more stably during extrusion, thereby improving the structural stability of the door seal 23. Moreover, the third wing part can better adapt to the assembly tolerance between the door body 2 and the cabinet 1, further improving the sealing performance of the door seal 23.

[0140] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the scope of the present application is limited only by the appended claims.
