[0026] The technical solutions in the embodiments (or “modes of implementation”) of the present application will be described clearly and completely below with reference to the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0027] If the application embodiments involve terms indicating direction or position relationship (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative position relationship, movement, etc. between components in a certain posture (as shown in the drawings); if the posture changes, the direction indication or position relationship will also change accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0028] The reference in the specification to any prior art does not constitute nor imply an admission that the prior art is part of the common general knowledge of the skilled person in the respective field of technology, or that the prior art is known to be relevant to an attempt to solve any problem with which the application deals, or that the prior art can be reasonably interpreted as suggesting the combination of the features recited in any claim of the application.

[0029] Since the refrigeration assembly is pushed into the rear side of the cabinet from the rear to the front, when the refrigeration assembly is installed in place, there will be a cold leakage between the refrigeration assembly and the rear plate of the cabinet. Even if a sealing element is arranged between the refrigeration assembly and the rear plate, the sealing effect is poor. In addition, the refrigerator is usually placed in a position close to the wall, which will cause the refrigeration assembly installed on the rear side to be inconvenient to maintain.

[0030] Therefore, the refrigerator provided by the application can avoid the gap between the rear part of the refrigeration assembly and the rear plate after the refrigeration assembly is slid into place relative to the cabinet, thereby reducing cold leakage.

[0031] Please refer to FIGS. 1-3, the refrigerator provided by the application comprises a cabinet 1 and a refrigeration assembly 2. As shown in FIG. 1, the front side of the cabinet 1 is provided with an opening 10. As shown in FIG. 2, the cabinet 1 comprises two side plates 11 located on opposite sides of the opening 10 and a rear plate 12 arranged opposite to the opening 10. The inner side of each of the two side plates 11 is provided with a sliding part 111 extending from front to back. As shown in FIG. 3, the side of the refrigeration assembly 2 is provided with a sliding matching part 21 matched with the sliding part 111, so that the refrigeration assembly 2 can gradually slide from front to back to the bottom of the cabinet 1 through the opening 10; after the refrigeration assembly 2 is slid into place, the rear part of the refrigeration assembly 2 abuts against the rear plate 12.

[0032] In the above scheme, the cabinet 1 can provide a space for the refrigeration unit 2 to slide from front to back, and a sliding part 111 extending from front to back is arranged on the inner side of the side plate 11. When the refrigeration unit 2 is slid from front to back to the position, the rear part of the refrigeration unit 2 can abut against the rear plate 12, so that the gap between the rear part of the refrigeration unit 2 and the rear plate 12 can be avoided as much as possible, and the situation that the cold energy in the refrigerator leaks from the gap between the rear part of the refrigeration unit 2 and the rear plate 12 can be reduced. In addition, the refrigeration unit 2 can be pulled out from the front of the cabinet 1, which is convenient for the maintenance or replacement of the refrigeration unit 2.

[0033] Please continue to refer to FIG. 2. In an embodiment, the sliding part 111 gradually inclines upward from front to back along the inner side of the side plate 11. Thus, the refrigeration unit 2 can gradually slide upward from front to back to abut against the rear part of the cabinet 1. Of course, in other embodiments, the sliding part 111 can also extend in a horizontal direction from front to back along the inner side of the side plate 11.

[0034] Please refer to FIGS. 2 and 3. In an embodiment, the cabinet 1 further includes a top plate 13. The side plate 11 and the rear plate 12 are connected to the top plate 13, respectively. The length of the rear plate 12 extending downward from the top plate 13 is less than the length of the side plate 11 extending downward from the top plate 13. After the refrigeration unit 2 is slid to the position, the rear part of the refrigeration unit 2 abuts against the lower wall surface 121 of the rear plate 12. Thus, after the refrigeration unit 2 is slid to the position, at least part of the structure of the refrigeration unit 2 can be used to compensate for the length of the rear plate 12 to avoid occupying too much space inside the cabinet 1, which is convenient for the miniaturization design of the refrigerator, while reducing the cold leakage.

[0035] For example, as shown in FIGS. 3 and 4, the rear part of the refrigeration unit 2 is provided with a rear abutting part 23 for abutting against the rear plate 12 of the refrigerator. The refrigeration unit 2 and the rear plate 12 form a seal to prevent cold leakage. In an embodiment, the rear abutting part 23 includes a rear abutting surface 231 arranged in parallel with respect to the horizontal plane. Thus, the rear abutting surface 231 is convenient for abutting against the lower wall surface 121 of the rear plate 12.

[0036] It should be noted that the top plate 13, the rear plate 12 and the side plate 11 can be integrally formed or separately processed and then spliced together. The splicing methods include but are not limited to bolt fastening connection.

[0037] Please continue to refer to FIG. 2. In an embodiment, the bottom of the cabinet 1 is not provided with a cabinet bottom plate. Thus, during the sliding process of the refrigeration unit 2 relative to the cabinet 1, the cabinet bottom plate can be avoided from interfering with the refrigeration unit 2. After the refrigeration unit 2 is slid to the position, the bottom of the refrigeration unit 2 can be regarded as the cabinet bottom plate of the bottom of the cabinet 1.

[0038] Of course, in other embodiments, the bottom of the box 1 can also be provided with a box bottom plate, but in order to avoid interference of the box bottom plate during sliding of the refrigeration unit 2, the shortest distance between the box bottom plate and the sliding portion 111 is greater than the height of the refrigeration unit 2. After the refrigeration unit 2 is slid into place, a certain space is formed between the bottom of the refrigeration unit 2 and the box bottom plate, so as to facilitate arrangement of other components of the refrigerator.

[0039] Please continue to refer to FIGS. 2 and 3, in an embodiment, after the refrigeration unit 2 is slid into place, the plane on which the bottom of the refrigeration unit 2 is located is not higher than the plane on which the bottom of the side plate 11 is located. Thus, after the refrigeration unit 2 is slid into place, the refrigeration unit 2 can be prevented from protruding from the side plate 11, and the overall structure of the refrigerator can be further miniaturized.

[0040] Please refer to FIGS. 2 and 5, in an embodiment, the portion of the side plate 11 that exceeds the rear plate 12 in the length direction is provided with the sliding portion 111. The side plate 11 is also provided with a boss portion 112 that protrudes inwardly, and the boss portion 112 is located above the sliding portion 111. After the refrigeration unit 2 is slid into place, the side of the refrigeration unit 2 abuts against the lower end surface 1121 of the boss portion 112. Thus, by closely abutting between the side of the refrigeration unit 2 and the side plate 11, interference between cold energy inside the refrigerator and heat generated by the refrigeration unit 2 through the gap between the side plate 11 and the refrigeration unit 2 can be avoided, and mutual isolation of the spaces in which they are respectively located can be achieved.

[0041] Please refer to FIGS. 3 and 5, in an embodiment, the side of the refrigeration unit 2 is provided with a side abutting surface 222 for cooperating with the lower end surface 1121 of the boss portion 112; the side abutting surface 222 and the lower end surface 1121 of the boss portion 112 are both arranged parallel to the horizontal plane. Thus, the inclination angle of the side abutting surface 222 and the boss portion 112 can be prevented from being too large, and interference with the process of gradually sliding the refrigeration unit 2 upward from front to back can be avoided, so as to affect sliding of the refrigeration unit 2 into place.

[0042] In another embodiment, the lower end surface 1121 of the boss portion 112 and the side abutting surface 222 are both arranged inclined to the horizontal plane. The inclination angle of the lower end surface 1121 of the boss portion 112 to the horizontal plane is α, the inclination angle of the sliding portion 111 to the horizontal plane is β, and the angle of the inclination angle α is smaller than the angle of the inclination angle β. Thus, interference with the process of gradually sliding the refrigeration unit 2 upward from front to back can be avoided, so as to affect sliding of the refrigeration unit 2 into place.

[0043] Referring to Figures 3 and 4, in one embodiment, the refrigeration unit 2 has a side abutment 22 on its side, which is located above the sliding mating part 21. The side abutment 22 includes an abutment protrusion extending from the refrigeration unit 2. The abutment protrusion forms a side abutment surface 222 on the side opposite to the sliding mating part 21. In another embodiment, the abutment protrusion forms a vertical abutment surface 221 on the side opposite to the refrigeration unit 2, which is perpendicular to the horizontal plane. Thus, the vertical abutment surface 221 can abut against the side plate 11 in the left-right direction of the housing 1, thereby sealing the refrigeration unit 2 with the side plate 11 in the left-right direction and preventing cold leakage.

[0044] As shown in Figure 5, in one embodiment, the sliding part 111 includes a slide rail 1111, the width of which gradually increases from front to back. As shown in Figure 4, the sliding mating part 21 includes a groove 211, the width of which also gradually increases from front to back, matching the width of the slide rail 1111. During the process of the refrigeration unit 2 sliding relative to the housing 1 from front to back, the front part of the slide rail 1111 on the side wall of the housing 1 should first engage with the rear part of the groove 211 of the refrigeration unit 2, and then the refrigeration unit 2 should gradually slide backward, ultimately engaging the front part of the groove 211 of the refrigeration unit 2 with the front part of the slide rail 1111 on the side wall of the housing 1. Based on this, by setting the width of the slide rail 1111 and the groove width of the slide groove 211 to gradually increase from front to back, when the front part of the slide rail 1111 provided on the side wall of the housing 1 first mates with the rear part of the slide groove 211 of the refrigeration unit 2, the end with the smaller width of the slide rail 1111 is inserted into the end with the larger width of the slide groove 211 first. This can reduce the insertion accuracy of the front part of the slide rail 1111 and improve the installation efficiency of the slide rail 1111 and the slide groove 211.

[0045] In one embodiment, the sliding part 111 includes a groove 211, the width of which gradually decreases from front to back. The sliding mating part 21 includes a slide rail 1111, the width of which also gradually decreases from front to back, matching the width of the groove 211. During the process of the refrigeration unit 2 sliding relative to the housing 1 from front to back, the front part of the groove 211 on the side wall of the housing 1 should first engage with the rear part of the slide rail 1111 of the refrigeration unit 2, and then the refrigeration unit 2 should gradually slide backward, ultimately engaging with the rear part of the groove 211 on the side wall of the housing 1 with the rear part of the slide rail 1111 of the refrigeration unit 2. Based on this, by setting the width of the slide rail 1111 and the groove width of the slide groove 211 to gradually decrease from front to back, when the front part of the slide groove 211 provided on the side wall of the housing 1 first mates with the rear part of the slide rail 1111 of the refrigeration unit 2, the narrower end of the slide rail 1111 is inserted into the wider end of the slide groove 211 first. This can reduce the insertion accuracy of the front part of the slide rail 1111 and improve the installation efficiency of the slide rail 1111 and the slide groove 211.

[0046] Referring to Figures 4 and 6, in one embodiment, the narrower end of the slide groove 211 is configured as a sealing structure 212. After the refrigeration unit 2 slides into place, the end face of the narrower end of the slide rail 1111 is clearance-fitted with the sealing structure 212. Therefore, after the refrigeration unit 2 slides into place, because there is still a certain gap between the end face of the narrower end of the slide rail 1111 and the sealing structure 212, the housing 1 can subsequently use its own weight to cause the slide rail 1111 to slide further towards the sealing structure 212 relative to the slide groove 211, resulting in a higher degree of compression at the contact point between the housing 1 and the refrigeration unit 2, further reducing the risk of cold leakage.

[0047] Referring to Figures 6 and 7, in one embodiment, the refrigerator includes an assembly transition state and a final assembly state. When the refrigeration unit 2 is pushed, the slide rail 1111 is configured to slide to a preset sliding position of the slide groove 211, so that the refrigerator is in the assembly transition state. After the slide rail 1111 reaches the preset sliding position, the slide rail 1111 is also configured to continue sliding towards the end cap structure 212 under the weight of the cabinet 1, so that the refrigeration unit 2 slides into place, so that the refrigerator is in the final assembly state.

[0048] As shown in Figure 7, when the slide rail 1111 reaches the preset sliding position, the distance between the end face of the narrower end of the slide rail 1111 and the sealing structure 212 is d1. As shown in Figure 6, when the refrigeration unit 2 slides into place, the distance between the end face of the narrower end of the slide rail 1111 and the sealing structure 212 is d2; where d1 > d2. Therefore, by utilizing the secondary displacement generated by the gravity of the cabinet 1, the leakage of cold air between the rear panel 12 of the cabinet 1 and the rear of the refrigeration unit 2 can be reduced. For example, in the transitional assembly state, the rear panel 12 of the cabinet 1 can initially abut against the rear of the refrigeration unit 2; subsequently, when the refrigerator is in the final assembly state, the rear panel 12 of the cabinet 1 can abut against the rear of the refrigeration unit 2 more tightly. In other words, in the transitional assembly state, the contact force between the rear panel 12 of the housing 1 and the rear of the refrigeration unit 2 is less than that in the final assembly state. This further reduces cold leakage. Of course, in other embodiments, as shown in Figure 7, in the transitional assembly state, the rear panel 12 of the housing 1 may not contact the rear of the refrigeration unit 2, while in the final assembly state, the rear panel 12 of the housing 1 may contact the rear of the refrigeration unit 2.

[0049] In one embodiment, the refrigerator further includes a resilient seal (not shown) disposed between the side panel 11 and the side of the refrigeration unit 2. In another embodiment, the resilient seal may also be disposed between the rear panel 12 and the rear of the refrigeration unit 2. Of course, in other embodiments, the resilient seal may be disposed both between the side panel 11 and the side of the refrigeration unit 2 and between the rear panel 12 and the rear of the refrigeration unit 2.

[0050] When the refrigerator is in the assembly transition state and / or the final assembly state, the elastic seal is in a compressed state. Therefore, the elastic seal can be used to increase the sealing performance between the cabinet 1 and the refrigeration unit 2.

[0051] In one embodiment, the connection between the rear panel 12, the top panel 13, and the side panel 11 is detachable. Therefore, the housing 1 can be customized according to actual usage needs, saving transportation space and facilitating flexible assembly.

[0052] In one embodiment, among the rear panel 12, the top panel 13, and the two side panels 11, one of the panels connected in pairs is the first panel A, and the other of the panels connected in pairs is the second panel B.

[0053] For example, when the rear panel 12 and the top panel 13 are connected, if the rear panel 12 is the first box panel A, then the top panel 13 is the second box panel B; conversely, if the top panel 13 is the first box panel A, then the rear panel 12 is the second box panel B. As another example, as shown in Figure 8, when the two side panels 11 are connected, if one side panel 11 is the first box panel A, then the other side panel 11 is the second box panel B.

[0054] Referring to Figures 8 and 9, both the first panel A and the second panel B include an outer shell 14, an inner liner 15, and a heat insulation plate 314 located between the outer shell 14 and the inner liner 15. At least a partial orthographic projection of the heat insulation plate 314 of the first panel A onto the direction towards the second panel B lies within the heat insulation plate 314 of the second panel B. In other words, the orthographic projection of the heat insulation plate 314 of the first panel A onto the heat insulation plate 314 of the second panel B forms a projection area s. Therefore, during the connection process between the first panel A and the second panel B, the heat insulation plate 314 of the first panel A and the heat insulation plate 314 of the second panel B can overlap to prevent cold leakage from the connection point between the first panel A and the second panel B.

[0055] Please refer to Figure 8. In one embodiment, both the inner lining 15 of the first panel A and the inner lining 15 of the second panel B include an inwardly protruding boss 112. The boss 112 has a mounting groove 1122 for mounting the heat insulation plate 314 on the side facing the outer shell 14. By mounting the heat insulation plate 314 in the mounting groove 1122 provided in the boss 112, the overlap area of ​​two adjacent heat insulation plates 314 can be further increased by the boss 112, thereby further reducing the risk of cold leakage.

[0056] Referring to Figures 9 and 10, in one embodiment, the inner lining 15 of the first panel A further includes an insertion portion disposed on the protrusion portion 112, and the inner lining 15 of the second panel B further includes an insertion mating portion disposed on the protrusion portion 112; the insertion portion and the insertion mating portion are inserted into each other. Thus, the inner lining 15 of the panel can be pre-fixed through an insertion connection, avoiding displacement during subsequent fixing and improving subsequent fixing efficiency.

[0057] Referring to Figures 9 and 10, in one embodiment, the boss portion 112 includes a boss sidewall 1123 formed along the thickness direction. The insertion portion of the first panel A includes a plurality of wedge-shaped plugs 151 spaced apart from the boss sidewall 1123. The insertion mating portion of the second panel B includes a plurality of wedge-shaped grooves 152 spaced apart from the boss sidewall 1123. The insertion mating of the plurality of wedge-shaped plugs 151 and the plurality of wedge-shaped grooves 152 can improve the connection stability of the panel liner 15. Of course, in other embodiments, the specific structure of the insertion portion and the insertion mating portion is not limited to this.

[0058] Please refer to Figures 9 and 10. In one embodiment, the insertion portion of the first panel A further includes a wedge-shaped groove 153 disposed between two adjacent wedge-shaped plugs 151, and the insertion mating portion of the second panel B further includes a wedge-shaped boss 154 disposed between two adjacent wedge-shaped grooves 152; the wedge-shaped groove 153 and the wedge-shaped boss 154 are inserted into each other. Thus, by utilizing the insertion mating of the wedge-shaped groove 153 and the wedge-shaped boss 154, a double insertion mating structure can be formed, improving the connection reliability of the inner lining 15 of the first panel A and the inner lining 15 of the second panel B.

[0059] Please refer to Figures 9 and 10. In one embodiment, the inner lining 15 of the first panel A further includes a first fastening hole 156 disposed on the side wall 1123 of the boss, and the inner lining 15 of the second panel B further includes a second fastening hole 155 disposed on the side wall 1123 of the boss. The first fastening hole 156 and the second fastening hole 155 are used for fasteners to pass through to achieve locking. This improves the robustness of the connection of the inner lining 15 and prevents deformation of the inner lining 15.

[0060] For example, the first fastening hole 156 may be provided on the wedge-shaped plug 151 provided on the inner lining 15 of the first panel A, and / or, the first fastening hole 156 may be provided on the wedge-shaped groove 153 provided on the inner lining 15 of the first panel A. The second fastening hole 155 may be provided on the wedge-shaped groove 152 provided on the inner lining 15 of the second panel B, and / or, the second fastening hole 155 may be provided on the wedge-shaped boss 154 provided on the inner lining 15 of the second panel B.

[0061] Referring to Figure 2, in one embodiment, the outer shells 14 of the two side panels 11 have flanges 141 formed on the side facing the opening 10. The flanges 141 formed by the two side panels 11 extend outwards in a direction away from each other, and are used to engage with the door seal 312 as shown in Figure 12. This allows for increased structural strength of the side panels 11 while also providing space for the door seal 312 to engage.

[0062] Referring to Figure 3, in one embodiment, the refrigeration unit 2 has a metal strip 24 on its bottom front side for fitting against the refrigerator door seal 312. In one embodiment, the refrigeration unit 2 also has a hinge mounting part 25 on its bottom front side for mounting the hinge of the refrigerator door 31. Exemplarily, the hinge mounting part 25 and the metal strip 24 are located at opposite ends of the bottom front side of the refrigeration unit 2.

[0063] It should be noted that after the refrigeration unit 2 is installed with the hinges, and the refrigerator door assembly is rotatably connected to the refrigeration unit 2 through the hinges, since the door assembly is also rotatably connected to one side of the cabinet 1, the hinges and the door 31 can prevent the refrigeration unit 2 from retracting.

[0064] In one embodiment, referring to Figure 11, the refrigerator further includes a door assembly 3, which includes a door 31 and a mounting bracket 32. The mounting bracket 32 ​​includes multiple separately arranged strip supports 321 and multiple inserts 322. The two ends of each strip support 321 along its length are respectively spliced ​​with the inserts 322. The multiple strip supports 321 and the multiple inserts 322 together form a mounting bracket 32 ​​for mounting the door 31. The mounting bracket 32, flexibly assembled from the strip supports 321 and inserts 322, can match different installation requirements for doors 31 of different sizes, thus offering greater versatility. Furthermore, by placing the inserts 322 at the ends of the strip supports 321, the load borne by the strip supports 321 can be shared, reducing the risk of deformation of the strip supports 321.

[0065] In one embodiment, the plurality of inserts 322 are located at the corners of the mounting bracket 32, and the strip bracket 321 is located between two adjacent inserts 322, engaging with the inclined surfaces of the inserts 322. Thus, when the strip bracket 321 and the inserts are engaged by the inclined surfaces, a compressive force is generated between them when they jointly bear external loads, similar to the locking effect of a wedge, making the engagement between the inserts 322 and the strip bracket 321 more secure, preventing loosening, and improving the overall strength of the mounting bracket 32. Of course, in other embodiments, the inserts 322 and the strip bracket 321 can also be engaged by a planar fit.

[0066] Referring to Figures 12 and 13, in one embodiment, the door 31 includes a door shell 311 located outside the mounting bracket 32. The door shell 311 includes a door shell body 3111 and a door shell edging 3112 formed by bending inward from the door shell body 3111. The door shell edging 3112 covers the outer peripheral edge 323 of the mounting bracket 32. This allows for the formation of a mounting surface for the door shell 311 on the outer peripheral edge 323 of the mounting bracket 32. By covering the outer peripheral edge 323 of the mounting bracket 32 ​​with the door shell edging 3112, the area enclosed by the mounting bracket 32 ​​can be made smoother and more seamless, avoiding the presence of structures such as the door shell 311 that could affect the assembly of the insulation panel 314 within the area.

[0067] It should be noted that the portions of the strip bracket 321 and the insert 322 located on the outer peripheral edge 323 of the mounting bracket 32 ​​both form mounting surfaces for mounting the door shell 311.

[0068] Referring to Figure 13, in one embodiment, the door shell edging 3112 extends further inward toward the mounting bracket 32 ​​to form a snap-fit ​​surface 3113 for engaging with the inner side of the mounting bracket 32. Thus, by engaging the snap-fit ​​surface 3113 with the inner side of the mounting bracket 32, the door shell 311 can be mounted on the mounting bracket 32, preventing displacement. Exemplarily, the inner side of the mounting bracket 32 ​​is provided with a door shell snap-fit ​​portion 327. One of the snap-fit ​​surface 3113 and the door shell snap-fit ​​portion 327 has a snap-fit ​​groove, and the other has a snap-fit ​​protrusion that engages with the snap-fit ​​groove. For example, when the snap-fit ​​surface 3113 has a snap-fit ​​groove, the door shell snap-fit ​​portion 327 has a snap-fit ​​protrusion. In other embodiments, when the snap-fit ​​surface 3113 has a snap-fit ​​protrusion, the door shell snap-fit ​​portion 327 has a snap-fit ​​groove.

[0069] When the door shell 311 is installed on the outside of the mounting bracket 32, the door shell edging 3112 extends from the outside of the mounting bracket 32, around the outer peripheral edge 323 of the mounting bracket 32, to the inside of the mounting bracket 32. Then, the snap-fit ​​surface 3113 formed by the door shell edging 3112 continues to extend and engages with the door shell snap-fit ​​part 327 provided on the inside of the mounting bracket 32. This ensures that the area enclosed by the mounting bracket 32 ​​is smoother and easier to install the heat insulation board 314 in this area.

[0070] It should be noted that the portions of the strip bracket 321 and the insert 322 located inside the mounting bracket 32 ​​both form the aforementioned snap-fit ​​surface 3113.

[0071] Referring to Figures 12 and 14, in one embodiment, the cabinet door 31 further includes a door seal 312 and a door liner 313. Both the door seal 312 and the door liner 313 are located inside the mounting frame 32. The mounting frame 32 has a door seal engaging portion 325 and a door liner engaging portion 326 on its inner side, with the door seal engaging portion 325 closer to the outer peripheral edge 323 of the mounting frame 32 than the door liner engaging portion 326. The door seal engaging portion 325 engages with the door seal 312, and the door liner engaging portion 326 engages with the door liner 313. By providing the door seal engaging portion 325 closer to the outer peripheral edge 323 on the inner side of the mounting frame 32, and the door liner engaging portion 326 farther from the outer peripheral edge 323 on the inner side of the mounting frame 32, interference with the subsequent installation of the door seal 312 can be avoided after the door liner 313 is installed. Furthermore, by placing both the door seal snap-fit ​​part 325 and the door liner snap-fit ​​part 326 on the inner side of the mounting bracket 32, the area enclosed by the mounting bracket 32 ​​can be made smoother and more seamless, avoiding the presence of grooves or other structures in the door liner 313 that could affect the assembly of the heat insulation board 314 within the area.

[0072] It should be noted that the inner side of the mounting bracket 32 ​​generally refers to the side of the mounting bracket 32 ​​facing the interior of the refrigerator's storage compartment, while the outer side of the mounting bracket 32 ​​refers to the side of the mounting bracket 32 ​​facing the outside of the refrigerator, opposite to the direction of the inner side of the mounting bracket 32. Furthermore, the portions of the strip bracket 321 and the insert 322 located on the inner side of the mounting bracket 32 ​​are both provided with a door seal latching portion 325 and a door liner latching portion 326.

[0073] Referring to Figures 12 and 15, in one embodiment, the door 31 further includes a heat insulation panel 314. The door shell 311, the door liner 313, and the inner peripheral edge 324 of the mounting bracket 32 ​​together enclose a receiving space 316. The heat insulation panel 314 is disposed in the receiving space 316 and is in contact with the inner peripheral edge 324 of the mounting bracket 32. This allows the heat insulation panel 314 to completely fill the entire receiving space 316, preventing gaps between the heat insulation panel 314 and the inner peripheral edge 324 of the mounting bracket 32 ​​that could lead to cold leakage. Exemplarily, the heat insulation panel 314 includes, but is not limited to, foam board or vacuum insulation panel (VIP board).

[0074] Referring to Figures 15 and 16, in one embodiment, the door seal 312 surrounds the door liner 313, with a gap 315 between them. At least one of the door seal latching portion 325 and the door liner latching portion 326 can extend into the gap 315. This allows for a more compact design of the door seal latching portion 325 and the door liner latching portion 326, and when at least one of them engages with at least one of the door seal 312 and the door liner 313, it can effectively conceal the gap 315.

[0075] Please refer to Figure 15. In one embodiment, the door liner 313 includes a door liner body 3131 and a door liner flange 3132 extending outwardly from the door liner body 3131. The door liner snap-fit ​​portion 326 includes a door liner snap-fit ​​groove, one side of which can extend into the gap 315 and snap-fit ​​with the door liner flange 3132. Thus, after the door liner snap-fit ​​portion 326 and the door liner flange 3132 are snap-fitted together, the door liner body 3131, the door shell body 3111, and the inner peripheral edge 324 of the mounting bracket 32 ​​can together form a square receiving space 316, which facilitates the installation of the square heat insulation plate 314.

[0076] It should be noted that the quantity of 314 insulation panels is not specifically limited here and can be freely selected according to actual design requirements.

[0077] Please continue referring to Figures 15 and 16. In one embodiment, the door seal snap-fit ​​portion 325 includes a door seal snap-fit ​​groove; the door seal snap-fit ​​groove is located above the door liner snap-fit ​​groove. The door seal 312 includes a snap-fit ​​protrusion 3121; the snap-fit ​​protrusion 3121 is spaced apart from the door liner flange 3132 and engages with the door seal snap-fit ​​groove.
