Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a refrigerator. Background Technology

[0002] The refrigeration unit of a refrigerator is usually installed at the rear of the refrigerator. During the operation of the refrigerator, the heat generated by the refrigeration unit can be dissipated from the rear in a timely manner to avoid affecting the temperature inside the storage space.

[0003] Because the refrigeration unit is pushed into the rear of the refrigerator from back to front, cold air leakage will occur between the refrigeration unit and the rear panel of the refrigerator after installation. Even with a seal between the refrigeration unit and the rear panel, the sealing effect is poor. Furthermore, refrigerators are usually placed against a wall, making maintenance of the rear-mounted refrigeration unit inconvenient. Summary of the Invention

[0056] The technical solutions in the embodiments (or "implementations") of this application will now be clearly and completely described with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0057] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0058] Please see Figures 1 to 3 The refrigerator provided in this application includes a cabinet 1 and a refrigeration unit 2. For example... Figure 1 As shown, the front side of the housing 1 has an opening 10. Figure 2 As shown, the housing 1 includes two side panels 11 located on opposite sides of the opening 10 and a rear panel 12 opposite to the opening 10. Each of the two side panels 11 has a sliding portion 111 extending from front to back on its inner side. Figure 3 As shown, the side of the refrigeration unit 2 is provided with a sliding engagement part 21 that cooperates with the sliding part 111, so that the refrigeration unit 2 can gradually slide from front to back to the bottom of the box 1 through the opening 10; after the refrigeration unit 2 slides into place, the rear part of the refrigeration unit 2 abuts against the rear plate 12 of the box.

[0059] In the above design, the cabinet 1 provides space for the refrigeration unit 2 to slide from front to back, and a sliding part 111 extending from front to back is provided on the inner side of the cabinet side panel 11. When the refrigeration unit 2 slides into place from front to back, the rear part of the refrigeration unit 2 can abut against the rear panel 12 of the cabinet. This can minimize the gap between the rear part of the refrigeration unit 2 and the rear panel 12 of the cabinet, reducing the leakage of cold air from the rear part of the refrigeration unit 2 to the rear panel 12 of the cabinet. In addition, the refrigeration unit 2 can be pulled out from the front of the cabinet 1, facilitating the maintenance or replacement of the refrigeration unit 2.

[0060] Please continue reading. Figure 2 In one embodiment, the sliding portion 111 extends gradually upward from front to back along the inner side of the side panel 11 of the housing. Thus, the refrigeration unit 2 can slide gradually upward from front to back until it abuts against the rear of the housing 1. Of course, in other embodiments, the sliding portion 111 may also extend horizontally from front to back along the inner side of the side panel 11 of the housing.

[0061] Please see Figure 2 and Figure 3In one embodiment, the cabinet 1 further includes a top panel 13. The side panels 11 and the rear panel 12 are respectively connected to the top panel 13. The length of the rear panel 12 extending downwards from the top panel 13 is less than the length of the side panels 11 extending downwards from the top panel 13. After the refrigeration unit 2 slides into place, the rear part of the refrigeration unit 2 abuts against the lower wall surface 121 of the rear panel 12. Therefore, after the refrigeration unit 2 slides into place, while reducing cold leakage, at least a portion of the structure of the refrigeration unit 2 can also be used to compensate for the length of the rear panel 12, so as to minimize the occupation of excessive space inside the cabinet 1 and facilitate the miniaturization design of the refrigerator.

[0062] For example, such as Figure 3 and Figure 4 As shown, the refrigeration unit 2 has a rear abutment member 23 at its rear for abutting against the rear panel 12 of the refrigerator body. This creates a seal between the refrigeration unit 2 and the rear panel 12, preventing cold leakage. In one embodiment, the rear abutment member 23 includes a rear abutment surface 231 arranged parallel to the horizontal plane. This facilitates abutting against the lower wall surface 121 of the rear panel 12.

[0063] It should be noted that the top panel 13, the rear panel 12, and the side panels 11 of the enclosure can be integrally formed, or they can be processed separately and then assembled together. Among them, the assembly method includes, but is not limited to, bolt fastening connection.

[0064] Please continue reading. Figure 2 In one embodiment, the bottom of the housing 1 does not have a bottom plate. Therefore, during the sliding process of the refrigeration unit 2 relative to the housing 1, interference from the bottom plate can be avoided. After the refrigeration unit 2 has slid into place, its bottom can be considered as the bottom plate of the housing 1.

[0065] Of course, in other embodiments, a bottom plate can also be provided at the bottom of the cabinet 1. However, in order to avoid interference during the sliding of the refrigeration unit 2, the shortest distance between the bottom plate and the sliding part 111 should be greater than the height of the refrigeration unit 2. After the refrigeration unit 2 slides into place, a certain space is formed between the bottom of the refrigeration unit 2 and the bottom plate of the cabinet to facilitate the arrangement of other components of the refrigerator.

[0066] Please continue reading. Figure 2 and Figure 3 In one embodiment, after the refrigeration unit 2 slides into place, the plane where the bottom of the refrigeration unit 2 is located is not higher than the plane where the bottom of the side panel 11 of the cabinet is located. Therefore, after the refrigeration unit 2 slides into place, it can be prevented from protruding from the side panel 11 of the cabinet, allowing for further miniaturization of the overall refrigerator structure.

[0067] Please see Figure 2 and Figure 5 In one embodiment, the sliding portion 111 is provided on the portion of the side panel 11 extending beyond the rear panel 12 along its length. The side panel 11 also has an inwardly protruding boss 112 located above the sliding portion 111. After the refrigeration unit 2 slides into place, the side of the refrigeration unit 2 abuts against the lower end face 1121 of the boss 112. Thus, by ensuring a tight fit between the side of the refrigeration unit 2 and the side panel 11, the cold air inside the refrigerator and the heat generated by the refrigeration unit 2 can be prevented from interfering with each other through the gap between the side panel 11 and the refrigeration unit 2, achieving mutual isolation between their respective spaces.

[0068] Please see Figure 3 and Figure 5 In one embodiment, the side of the refrigeration unit 2 is provided with a side abutment surface 222 for engaging with the lower end face 1121 of the boss portion 112; both the side abutment surface 222 and the lower end face 1121 of the boss portion 112 are arranged parallel to the horizontal plane. This avoids excessively large tilt angles between the side abutment surface 222 and the boss portion 112, which could interfere with the gradual upward sliding process of the refrigeration unit 2 from front to back, thus affecting the refrigeration unit 2's sliding into position.

[0069] In another embodiment, both the lower end face 1121 of the boss portion 112 and the side abutment surface 222 are inclined relative to the horizontal plane. The inclination angle of the lower end face 1121 of the boss portion 112 relative to the horizontal plane is α, and the inclination angle of the sliding portion 111 relative to the horizontal plane is β. The angle α is smaller than the angle β. This avoids interference with the gradual upward sliding process of the refrigeration unit 2 from front to back, thus preventing the refrigeration unit 2 from sliding into place.

[0070] Please see Figure 3 and Figure 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 protruding 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 panel 11 of the housing 1 in the left-right direction, so that the refrigeration unit 2 and the side panel 11 of the housing form a seal in the left-right direction, preventing cold leakage.

[0071] like Figure 5 As shown, in one embodiment, the sliding portion 111 includes a slide rail 1111, the width of which gradually increases from front to back. Figure 4 As shown, the sliding mating part 21 includes a groove 211, the width of which gradually increases from front to back, matching the width of the slide rail 1111. During the sliding process of the refrigeration unit 2 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.

[0072] 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.

[0073] Please see Figure 4 and Figure 6In 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 in clearance fit 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, thereby further reducing the risk of cold leakage.

[0074] Please see Figure 6 and Figure 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-sealing 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.

[0075] like Figure 7 As shown, 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. Figure 6 As shown, 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, the secondary displacement caused by the gravity of the cabinet 1 can reduce cold leakage between the rear panel 12 of the cabinet 1 and the rear of the refrigeration unit 2. 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. Then, 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 abutment force between the rear panel 12 of the cabinet 1 and the rear of the refrigeration unit 2 is less than that in the final assembly state. Therefore, cold leakage can be further reduced. Of course, in other embodiments, such as... Figure 7 As shown, in the transitional assembly state, the rear panel 12 of the housing 1 may not abut against the rear of the refrigeration unit 2, while in the final assembly state, the rear panel 12 of the housing 1 abuts against the rear of the refrigeration unit 2.

[0076] In one embodiment, the refrigerator further includes a resilient seal (not shown) disposed between the side panel 11 of the refrigerator body and the side of the refrigeration unit 2. In another embodiment, the resilient seal may also be disposed between the rear panel 12 of the refrigerator body 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 of the refrigerator body and the side of the refrigeration unit 2 and between the rear panel 12 of the refrigerator body and the rear of the refrigeration unit 2.

[0077] 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.

[0078] In one embodiment, the connection between the rear panel 12, the top panel 13, and the side panels 11 of the housing is detachable. Therefore, the housing 1 can be customized according to actual usage needs, saving transportation space and facilitating flexible assembly.

[0079] 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.

[0080] For example, when the rear panel 12 and the top panel 13 of the enclosure are connected, if the rear panel 12 is the first panel A, then the top panel 13 is the second panel B; conversely, if the top panel 13 is the first panel A, then the rear panel 12 is the second panel B. As another example... Figure 8 As shown, when two box side panels 11 are connected, if one box side panel 11 is the first box panel A, then the other box side panel 11 is the second box panel B.

[0081] Please see Figure 8 and Figure 9 Both the first cabinet panel A and the second cabinet panel B include an outer shell 14, an inner lining 15, and a door insulation panel 314 located between the outer shell 14 and the inner lining 15. At least a partial orthographic projection of the door insulation panel 314 of the first cabinet panel A onto the second cabinet panel B is located within the door insulation panel 314 of the second cabinet panel B. In other words, the orthographic projection of the door insulation panel 314 of the first cabinet panel A onto the door insulation panel 314 of the second cabinet panel B can form a projection area s. Therefore, during the connection process between the first cabinet panel A and the second cabinet panel B, the door insulation panels 314 of the first cabinet panel A and the second cabinet panel B can overlap to prevent cold leakage from the connection point between the first cabinet panel A and the second cabinet panel B.

[0082] Please continue reading. Figure 8 In one embodiment, the inner lining 15 of the first panel A and the inner lining 15 of the second panel B both include an inwardly protruding boss 112. The boss 112 has a mounting groove 1122 on the side facing the outer casing 14 for mounting the door insulation panel 314. By mounting the door insulation panel 314 within the mounting groove 1122 of the boss 112, the overlap area of ​​two adjacent door insulation panels 314 can be further increased by the boss 112, thereby further reducing the risk of cold leakage.

[0083] Please see Figure 9 and Figure 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.

[0084] Please continue reading. Figure 9 and Figure 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 connection stability of the panel liner 15 can be improved by the insertion and mating of the plurality of wedge-shaped plugs 151 and the plurality of wedge-shaped grooves 152. Of course, in other embodiments, the specific structure of the insertion portion and the insertion mating portion is not limited to this.

[0085] Please continue reading. Figure 9 and Figure 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.

[0086] Please continue reading. Figure 9 and Figure 10In 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.

[0087] 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.

[0088] Please see Figure 2 In one embodiment, the outer shell 14 of the two box side panels 11 has a flange 141 formed on the side facing the opening 10. The flanges 141 formed by the two box side panels 11 extend outwards in a direction away from each other, and the flanges 141 are used to... Figure 12 The door seal 312 shown is attracted to each other. This improves the structural strength of the side panel 11 of the enclosure while providing space for the door seal 312 to be attracted to each other.

[0089] Please see 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 another embodiment, the refrigeration unit 2 also has a hinge mounting part 25 on its bottom front side for mounting the refrigerator door 31 hinge. 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.

[0090] 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.

[0091] In one embodiment, see Figure 11The refrigerator also includes a door assembly 3, which comprises a door 31 and a mounting bracket 32. The mounting bracket 32 ​​includes multiple separately arranged strip supports 321 and multiple inserts 322. Each end of a strip support 321 is connected to an insert 322 along its length. 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 accommodate different installation requirements for doors 31 of different sizes, 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 distributed, reducing the risk of deformation of the strip supports 321.

[0092] 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.

[0093] Please see Figure 12 and Figure 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. Thus, a mounting surface for mounting the door shell 311 can be formed 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 avoids structures such as the door shell 311 flange 141 that could affect the assembly of the door insulation panel 314 within the area.

[0094] 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.

[0095] Please continue reading. Figure 13In 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 having a snap-fit ​​groove, and the other having 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.

[0096] 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, and 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 door heat insulation plate 314 in this area.

[0097] 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.

[0098] Please see Figure 12 and Figure 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. In addition, 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 door insulation panel 314 within the area.

[0099] 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.

[0100] Please see Figure 12 and Figure 15 In one embodiment, the door 31 further includes a door 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 door 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 door insulation panel 314 to completely fill the entire receiving space 316, preventing gaps between the door insulation panel 314 and the inner peripheral edge 324 of the mounting bracket 32 ​​that could lead to cold leakage. Exemplarily, the door insulation panel 314 includes, but is not limited to, foam board or VIP board (vacuum insulation panel).

[0101] Please see Figure 15 and Figure 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 these portions engages with at least one of the door seal 312 and the door liner 313, it can effectively conceal the gap 315.

[0102] Please continue reading. 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 wall 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 box door heat insulation panel 314.

[0103] It should be noted that the quantity of the 314 heat insulation panels for the cabinet door is not specifically limited here, and can be freely selected according to actual design requirements.

[0104] Please continue reading. Figure 15 and Figure 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 snaps into the door seal snap-fit ​​groove.
