[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0047] This application provides a refrigerator door assembly, which may be, for example, a French door refrigerator, a side-by-side refrigerator, or a cross-door refrigerator. For an example, please refer to... Figure 1-Figure 4 , Figure 1This is a structural schematic diagram of the door assembly provided in an embodiment of this application. Figure 2 for Figure 1 The structural diagram shown is an enlarged view of region A. Figure 3 for Figure 1 The exploded view of the door assembly shown. Figure 4 for Figure 3 The exploded view shown is an enlarged view of area B. The door assembly 10 includes a sliding door 100, a mounting bracket 200, and a guide rail assembly 300.

[0048] The mounting bracket 200 is fixedly installed on the pull-out door 100. One of the mounting bracket 200 and the guide rail assembly 300 has a insertion groove 310, and the other has a connector 210 fixed on it. The connector 210 is confined in the insertion groove 310 so that the mounting bracket 200 is assembled on the guide rail assembly 300. The guide rail assembly 300 is used to slide with the refrigerator's storage compartment and to slide the pull-out door 100 to open or close the storage compartment. The connector 210 includes a plug 211 and an elastic buckle 212 connected to the plug 211. A limiting groove 311 is provided on the inner side wall of the insertion groove 310. The insertion groove 310 is suitable for the plug 211 to be inserted through the groove 312, and the limiting groove 311 is suitable for the elastic buckle 212 to be engaged to restrict the movement of the plug 211 in its insertion direction H1.

[0049] Optional, such as Figure 1-Figure 4 The connector 210 can be fixedly connected to the mounting bracket 200, and a corresponding connector slot 310 can be formed on the guide rail assembly 300. In some other embodiments, the connector 210 can also be fixedly connected to the guide rail assembly 300, and a corresponding connector slot 310 can be formed on the mounting bracket 200.

[0050] It should be noted that the limiting groove 311 can be a groove with a closed bottom, or it can be... Figure 1-Figure 4 The groove shown is open at both ends and has through holes. The limiting groove 311 includes at least a first limiting sidewall (not shown) located in the insertion direction H1 of the plug 211. The first limiting sidewall is adapted to block between the groove 312 and the elastic buckle 212 to limit the movement of the elastic buckle 212 in the pull-out direction of the plug 211, thereby preventing the plug 210 from exiting the insertion groove 310 through the groove 312. In some embodiments, the limiting groove 311 also includes a second limiting sidewall (not shown) disposed opposite to the first limiting sidewall. When the elastic buckle 212 is engaged in the limiting groove 311, in the insertion and pull-out direction of the plug 211, the first limiting sidewall and the second limiting sidewall respectively block the two sides of the elastic buckle 212 to limit the movement of the elastic buckle 212 in the insertion and pull-out direction of the plug 211, thereby limiting the movement of the plug 210 in its insertion and pull-out direction.

[0051] During the actual installation of the door assembly 10, the guide rail assembly 300 can be slidably installed in the refrigerator's storage compartment first, and then the mounting bracket 200 is fastened to the pull-out door 100. Subsequently, the insert block 211 is gradually inserted into the insert groove 310 along the insertion direction H1 until the elastic buckle 212 on the insert block 211 is engaged in the limiting groove 311 to complete the installation. It should be noted that when the plug 211 is inserted into the insertion slot 310, the plug 211 is limited in the circumferential direction by the circumferential side wall of the insertion slot 310. When the elastic buckle 212 is engaged in the limiting slot 311, the movement of the elastic buckle 212 in the insertion direction H1 of the plug 211 is restricted by the inner wall of the limiting slot 311, so that the plug 211 cannot be pulled out of the insertion slot 310 through the slot 312. Thus, the plug 211 is locked in the insertion slot 310, so that the mounting bracket 200 is fixedly connected to the guide rail assembly 300.

[0052] The refrigerator door assembly 10 provided in this application embodiment has a connector 210 that is inserted into a connector groove 310 via a connector 211 and is limited in the circumferential direction. It is also limited in the insertion direction H1 by a snap-fit ​​212 that is engaged in a limiting groove 311. This allows the connector 210 to be secured in the connector groove 310, thereby mounting the bracket 200 on the guide rail assembly 300. This allows the pull-out door 100 to be pulled out and installed in the refrigerator's storage compartment. Compared to the existing screw installation method, the mounting bracket 200 and the guide rail assembly 300 are connected by the connector 210 and the connector groove 310 in this application, which can improve the installation efficiency of the door assembly 10.

[0053] For example, please refer to Figure 5 , Figure 5 This is a schematic diagram of the mounting bracket provided in an embodiment of this application. The mounting bracket 200 is a sheet metal part, including a bent and connected fixing part 220 and a mounting part 230. The fixing part 220 is adapted to be fixedly connected to the pull-out door 100. Optionally, the fixing part 220 is fixedly connected to the surface of the pull-out door 100 facing the refrigerator storage compartment by screws. The mounting part 230 extends in a direction perpendicular to the pull-out door 100. For example, there are two mounting brackets 200, symmetrically mounted on the left and right sides of the pull-out door 100, thus improving the stability of the pull-out door 100 when it is pulled out.

[0054] A connector 210 is fixedly connected to the mounting part 230. The connector 210 can be integrally formed with the mounting part 230 or it can be a separate component. For example, see [reference needed]. Figure 6 , Figure 6 for Figure 5The exploded view of the mounting bracket is shown. The mounting part 230 has a protruding connecting part 240. The plug-in part 210 is pocket-shaped and has a connecting groove 213. The connecting part 240 is inserted into the connecting groove 213 and is snapped into the connecting groove by a snap-fit ​​structure.

[0055] Optionally, the refrigerator includes a cabinet liner, which forms the refrigerator's cooling compartment. Sliding grooves are provided on two opposite inner side walls of the cabinet liner. For example, two guide rail assemblies 300 are provided corresponding to the mounting bracket 200. One end of each guide rail assembly 300 is slidably connected to the two opposite inner side walls of the cabinet liner via the sliding grooves, and the other end is connected to the mounting bracket 200. The guide rail assembly 300 can be as follows: Figure 1 The double-section rail shown can also be a multi-section rail, such as a three-section rail or a four-section rail.

[0056] For example, please refer to the section on double-section rails. Figure 7 , Figure 7 This is a schematic diagram of the guide rail assembly provided in an embodiment of this application. The guide rail assembly 300 includes a first guide rail 320 and a second guide rail 330. The first guide rail 320 is slidably connected to the storage compartment of the refrigerator. The second guide rail 330 has a insertion groove 310. By confining the insertion member 210 within the insertion groove 310, the second guide rail 330 is connected to the mounting bracket 200. Optionally, the mounting bracket 200 is positioned above the second guide rail 330; the insertion member 210 extends downwards along the height direction of the pull-out door 100; the opening 312 of the insertion groove 310 faces the mounting bracket 200.

[0057] In some embodiments, please refer to Figures 8-11 , Figure 8 This is a cross-sectional view of the connector provided in the embodiment of this application. Figure 9 This is a schematic diagram of the assembly of the connector and the connector slot provided in the embodiments of this application. Figure 10 This is a cross-sectional view of the connector and connector slot in a first assembly state according to an embodiment of this application. Figure 11 This is a cross-sectional view of the connector and the insertion slot provided in the application embodiment in a second assembled state. The elastic buckle 212 includes an elastic part 2121 and a buckling part 2122. The two ends of the elastic part 2121 are respectively connected to the insert block 211 and the buckling part 2122. The insert block 211 has a clearance hole 2111, which is disposed opposite to the buckling part 2122; Figure 8 As shown, when the insert 211 is inserted into the first position in the insertion slot 310, the latching part 2122 is pressed into the clearance hole 2111, and the elastic part 2121 is in an elastic deformation state; as Figure 9 As shown, when the insert 211 is inserted into the second position in the insertion slot 310, the elastic part 2121 is in a state of restoring deformation, so that the insert 211 moves away from the clearance hole 2111 and is inserted into the limiting slot 311.

[0058] Understandably, when the insert block 211 moves to the first position, the latching part 2122 is squeezed by the inner wall of the insertion groove 310 and extends into the relief hole 2111 to avoid interference between the latching part 2122 and the inner wall of the insertion groove 310, so that the insert block 211 can move toward the second position; after the insert block 211 moves to the second position, the latching part 2122 is no longer under pressure, so the elastic part 2121 can restore its elastic deformation and drive the latching part 2122 to leave the relief hole 2111 and engage in the limiting groove 311.

[0059] In one parallel embodiment, the elastic buckle 212 includes an elastic part 2121 and a buckling part 2122. The two ends of the elastic part 2121 are connected to the insert block 211 and the buckling part 2122, respectively. A clearance groove (not shown) is provided on the side wall of the insertion groove 310. The clearance groove is disposed opposite to the buckling part 2122. When the insert block 211 is inserted into the first position in the insertion groove 310, the buckling part 2122 is pressed into the clearance groove, and the elastic part 2121 is in an elastic deformation state. When the insert block 211 is inserted into the second position in the insertion groove 310, the elastic part 2121 is in a recovery deformation state, so that the insert block 211 moves away from the clearance groove and into the locking groove 311.

[0060] Optional, such as Figure 10-11 The insertion block 211 has a clearance hole 2111; elastic buckles 212 are respectively provided on both sides of the extension direction of the clearance hole 2111. The insertion groove 310 includes a first side wall 313 and a second side wall 314 arranged opposite to each other. The first side wall 313 and the second side wall 314 are respectively arranged opposite to the elastic buckles 212 on both sides of the clearance hole 2111. The first side wall 313 has a first limiting groove for the corresponding elastic buckle 212 to be engaged, and the second side wall 314 has a second limiting groove for the corresponding elastic buckle 212 to be engaged. Optionally, the first limiting groove includes a feature suitable for blocking the groove opening 312 and the corresponding buckle part 2122. The first limiting sidewall is between the two, and the latching part 2122 abuts against the first limiting sidewall. Simultaneously, the insertion groove 310 also includes a bottom end opposite to the groove opening 312. The second limiting groove includes a second limiting sidewall adapted to block the space between the bottom end and the corresponding latching part 2122, with the latching part 2122 abutting against the second limiting sidewall. Thus, the first and second limiting sidewalls respectively prevent the insertion member 210 from moving in the insertion and extraction directions, thereby fixing the insertion member 210 in its insertion and extraction directions. It should be noted that in the embodiment shown in the figure, both the first and second limiting grooves are grooves with open ends forming through holes. In other embodiments, the first and second limiting grooves can also be set as common recessed grooves.

[0061] In some embodiments, the insert block 211 has protruding ribs 214 on both sides in the first direction H2. The ribs 214 are adapted to abut against the inner wall of the insertion groove 310 to restrict the movement of the insert block 211 in the first direction H2, which is perpendicular to the insertion direction H1. The insert block 211 includes a free end 2112 located at the front side in the insertion direction. To facilitate the insertion of the connector 210 into the insertion groove 310, a guide slope can be formed on the end face of the rib 214 near the free end 2112.

[0062] In some embodiments, the sidewall of the insert 211, which is disposed opposite to it in the second direction H3, fits against the inner wall of the insertion groove 310, thereby restricting the movement of the insert 211 in the second direction H3. The second direction H3 is perpendicular to the first direction H2 and the insertion direction H1. In this way, the insert 210 is fixed in the first direction H2 and the second direction H3. Preferably, to ensure the stability of the connection, the insert 210 can be fixed in the first direction H2, the second direction H3, and the insertion direction H1, so that the mounting bracket 200 can be fixedly connected to the guide rail assembly 300.

[0063] In some embodiments, see Figure 1 and Figure 3 One of the mounting bracket 200 and the guide rail assembly 300 is provided with a positioning hole 340, and the other is fixed with a positioning hook 250. The positioning hook 250 is adapted to engage with the positioning hole 340 so that the guide rail assembly 300 limits the mounting bracket 200. Optionally, the positioning hook 250 can be fixed to the mounting bracket 200 and the positioning hole 340 can be provided on the guide rail assembly 300, or the positioning hook 250 can be fixed to the guide rail assembly 300 and the positioning hole 340 can be provided on the mounting bracket 200.

[0064] For example, see Figure 5-Figure 7 The second guide rail 330 is also provided with positioning holes 340, and the insertion groove 310 is spaced apart from the positioning holes 340. The mounting part 230 is correspondingly connected with spaced-apart positioning hooks 250 and insertion pieces 210. Preferably, the insertion groove 310 and the positioning holes 340 are respectively located near opposite ends of the second guide rail 330, and correspondingly, the positioning hooks 250 and insertion pieces 210 are also located near opposite ends of the second guide rail 330. This improves the stability of the connection between the guide rail assembly 300 and the mounting bracket 200.

[0065] The refrigerator door assembly 10 provided in this application embodiment has a connector 210 that is inserted into a connector groove 310 via a connector 211 and is limited in the circumferential direction. It is also limited in the insertion direction H1 by a snap-fit ​​212 that is engaged in a limiting groove 311. This allows the connector 210 to be secured in the connector groove 310, thereby mounting the bracket 200 on the guide rail assembly 300. This allows the pull-out door 100 to be pulled out and installed in the refrigerator's storage compartment. Compared to the existing screw installation method, the mounting bracket 200 and the guide rail assembly 300 are connected by the connector 210 and the connector groove 310 in this application, which can improve the installation efficiency of the door assembly 10.

[0066] This application also provides a refrigerator, for example, please refer to [link to example]. Figure 12 , Figure 12 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. The refrigerator 1 includes a cabinet 20 and a door assembly 10 as described in any of the above embodiments. The cabinet 20 forms a storage compartment, and the door assembly 10 is installed on the cabinet 20 for opening or closing the storage compartment. The storage compartment can be a refrigerator compartment, a freezer compartment, or a variable temperature compartment.

[0067] For example, the refrigerator 1 also includes a storage drawer adapted to be mounted on the mounting bracket 200; when the door assembly 10 is pulled out, it causes the storage drawer to slide into or out of the storage compartment.

[0068] In the refrigerator 1 provided in this application embodiment, the connector 210 is inserted into the connector slot 310 by the connector block 211 and is limited in the circumferential direction, and is locked into the limiting slot 311 by the elastic buckle 212 and is limited in the connector direction H1, so that the connector 210 is locked in the connector slot 310, thereby the mounting bracket 200 is installed on the guide rail assembly 300, so that the pull-out door 100 can be pulled out and installed in the refrigerator's storage compartment. Compared with the existing screw installation method, in this application, the mounting bracket 200 and the guide rail assembly 300 are connected by the connector 210 and the connector slot 310, which can improve the installation efficiency of the door assembly 10 on the cabinet 20.

[0069] The refrigerator door assembly and refrigerator provided in the embodiments of this application have been described in detail above.
