[0038] This application provides a door structure suitable for refrigerators, eliminating the need for screws and / or bolts to fix the drawer door to the guide rails, thus improving assembly efficiency and simplifying installation. The following description, in conjunction with the accompanying drawings, will illustrate this.

[0039] In the embodiments of this application, such as Figures 1 to 7 As shown, a door structure 1 is used in a refrigerator 100. The door structure 1 includes a door 11, a bracket 12, and a guide rail assembly 13. The bracket 12 connects the door 11 and the guide rail assembly 13. The guide rail assembly 13 includes a guide rail body 131 and a connecting part 132 disposed on the guide rail body 131. The guide rail body 131 is used to slide with the storage compartment 2 of the refrigerator 100 so that the door 11 can open or close the storage compartment 2. The connecting part 132 connects the bracket 12 and the guide rail body 131. The connecting part 132 is provided with a first connecting member 1321, and the bracket 12 is provided with a second connecting member 121. One of the first connecting member 1321 and the second connecting member 121 is a first protrusion, and the other is an elastic member. The elastic member is provided with a first through hole that is adapted to engage with the first protrusion.

[0040] In the above-mentioned door structure 1, the door body 11 and the guide rail body 131 do not need to be assembled with screws and / or bolts. The door body 11 and the guide rail body 131 are assembled into one unit by the adapter snap-fit ​​between the first connector 1321 and the second connector 121, which effectively improves the assembly efficiency of the door body 11 and simplifies the installation difficulty of the door body 11.

[0041] Furthermore, the elastic element can undergo elastic deformation when subjected to external force, which enables the size of the first through hole to be adaptively adjusted according to different external force magnitudes and / or the size of the first protrusion, so as to ensure good snap-fit ​​fastness between the first protrusion and the elastic element, and to provide good limiting effect on the bracket 12 in the X, Y and Z directions.

[0042] It should be noted that the first protrusion can be cylindrical, prismatic, spherical, frustum-shaped, etc., and the elastic element can be annular. The elastic element can be, for example, a plastic buckle. The first connector 1321 can be integrally formed with the connecting part 132, or the first connector 1321 can be fixed to the connecting part 132 by one or more of the following connection methods: riveting, welding, bonding, insertion, snap-fit, threaded connection, pin connection, elastic deformation connection, and locking connection. The second connector 121 can be integrally formed with the bracket 12, or the second connector 121 can be fixed to the bracket 12 by one or more of the following connection methods: riveting, welding, bonding, insertion, snap-fit, threaded connection, pin connection, elastic deformation connection, and locking connection.

[0043] In some embodiments of this application, see further reference. Figures 1 to 4 The first connector 1321 is an elastic member, and the second connector 121 is a first protrusion. The elastic member is riveted to the connecting part 132, and the first protrusion is integrally formed with the bracket 12. It can be understood that the first connector 1321 can also be the first protrusion, and the second connector 121 can be the elastic member.

[0044] To further improve the assembly tightness between the door body 11 and the guide rail body 131, in some embodiments of this application, please refer to... Figures 1 to 4 In the X direction, the bracket 12 also includes a hook 122 disposed on one side of the second connector 121. When the door 11 opens the storage room 2, the hook 122 is closer to the storage room 2 than the second connector 121. The guide rail assembly 13 also includes a first limiting groove 133. The first limiting groove 133 and the connecting part 132 enclose a first cavity 134. The hook head of the hook 122 passes through the first cavity 134 and abuts against at least one groove wall of the first limiting groove 133 to limit the bracket 12 in the Z direction, effectively improving the phenomenon of the door 11 tipping over due to its own weight.

[0045] Further reading Figures 1 to 4The first limiting groove 133 includes a third groove wall 1331, a fourth groove wall 1332, and a first groove bottom 1333. The third groove wall 1331 and the fourth groove wall 1332 are arranged opposite to each other and spaced apart in the X direction. The first groove bottom 1333 connects the third groove wall 1331 and the fourth groove wall 1332. The first groove bottom 1333 and the connecting part 132 are arranged opposite to each other in the Y direction. In other words, the third groove wall 1331, the fourth groove wall 1332, the first groove bottom 1333, and the connecting part 132 enclose a first cavity 134. The hook head of the hook 122 passes through the first cavity 134 and abuts against at least one of the third groove wall 1331 and the fourth groove wall 1332. Furthermore, in the X direction, the hook 122 is limited between the third groove wall 1331 and the fourth groove wall 1332, thereby limiting the bracket 12 in the X direction; in the Y direction, the hook 122 is limited between the first groove bottom 1333 and the connecting part 132, thereby limiting the bracket 12 in the Y direction.

[0046] To further improve the assembly tightness between the door body 11 and the guide rail body 131, in some embodiments of this application, please refer to... Figures 1 to 4 In the X direction, the bracket 12 further includes a buckle 123 disposed on one side of the second connector 121. The second connector 121 is disposed between the hook 122 and the buckle 123. The guide rail assembly 13 also includes a second limiting groove 135. The second limiting groove 135 and the connecting part 132 enclose a second cavity 136, and the buckle 123 is inserted into the second cavity 136. It can be understood that the buckle 123 is closer to the door body 11 than the hook 122 and the second connector 121. The buckle 123 is inserted into the second cavity 136 to achieve the function of auxiliary positioning and support for the door body 11. The structure of the second limiting groove 135 can be the same as that of the first limiting groove 133. For ease of assembly, the buckle head of the buckle 123 passes through the second cavity 136 without abutting against the groove wall of the second limiting groove 135.

[0047] It should be noted that when there are three connection points between the bracket 12 and the connecting part 132, the assembly process includes: first, locking the hook 122 into the first limiting groove 133 to fix the front end; then, locking the first connecting piece 1321 and the second connecting piece 121 to fix the middle end; finally, inserting the buckle 123 into the second cavity 136 to fix the rear end.

[0048] In some embodiments of this application, see further reference. Figures 1 to 4The guide rail body 131 and the connecting part 132 are both groove-shaped structures. The bottom of the groove of the guide rail body 131 is provided with a second protrusion 1311, and the connecting part 132 is engaged with the second protrusion 1311 to facilitate the assembly of the guide rail body 131 and the connecting part 132. It can be understood that, in order to further improve the connection tightness between the guide rail body 131 and the connecting part 132, one or more detachable connection methods can be added between the guide rail body 131 and the connecting part 132.

[0049] In some embodiments of this application, see further reference. Figures 1 to 4 In the X direction, the guide rail body 131 and the connecting part 132 partially overlap. On the one hand, this facilitates the guide rail body 131 to slide into or out of the storage compartment 2. On the other hand, it shortens the distance between the door 11 and the guide rail body 131 in the X direction, which helps to improve the utilization rate of the internal space of the refrigerator 100 and reduce the floor area of ​​the refrigerator 100.

[0050] In some embodiments of this application, see further reference. Figures 1 to 4 The width of the connecting portion 132 in the Z direction is smaller than the width of the guide rail body 131 in the Z direction, which can further improve the utilization rate of the internal space of the refrigerator 100. It should be noted that the width of the connecting portion 132 in the Z direction refers to the straight-line distance between the two farthest points on the outer periphery of the connecting portion 132, and the straight line connecting these two points is parallel to the Z direction; similarly, the width of the guide rail body 131 in the Z direction refers to the straight-line distance between the two farthest points on the outer periphery of the guide rail body 131, and the straight line connecting these two points is parallel to the Z direction.

[0051] In some embodiments of this application, see further reference. Figures 1 to 4 The bracket 12 includes a bracket body 124, a folded edge portion 125, and a connector 126. The bracket body 124 has a groove-shaped structure. The folded edge portion 125 is connected to one side of the groove wall of the bracket body 124. The connector 126 connects the door body 11 to the bracket body 124. A second connector 121 is disposed on the folded edge portion 125. It should be noted that when the bracket 12 includes a hook 122 and a buckle 123, the hook 122 and the buckle 123 are respectively disposed on the folded edge portion 125; the connector 126 is, for example, located at the end of the bracket body 124 away from the guide rail body 131.

[0052] This application embodiment also provides a refrigerator 100, which includes, but is not limited to, a side-by-side refrigerator, a T-type three-door refrigerator, a cross-door refrigerator, or a French door refrigerator, such as...

[0053] In some embodiments of this application, see further reference. Figures 1 to 7 The refrigerator 100 also includes a drawer 3, which is connected to a bracket 12. The guide rail body 131 slides relative to the storage compartment 2 so that the drawer 3 slides into or out of the storage compartment 2.

[0054] It is understood that there can be two brackets 12 and two guide rail assemblies 13. The two brackets 12 are respectively installed on the two side walls of the drawer 3 that are opposite each other in the Y direction. Correspondingly, the two guide rail assemblies 13 are respectively installed on the two side walls of the drawer 3 that are opposite each other in the Y direction. The inner wall of the storage compartment 2 is provided with a track for the guide rail body 131 to slide.

[0055] In some embodiments of this application, see further reference. Figure 3 as well as Figures 5 to 7 The drawer 3 is provided with a third connector 31. The support body 124 has a groove-shaped structure, including a first groove wall 1241 and a second groove wall 1242 arranged opposite to each other in the Z direction. The first groove wall 1241 is provided with a clearance opening 1243 for accommodating the third connector 31, and the folded edge 125 is connected to the second groove wall 1242. It should be noted that the third connector 31 can be, for example, a snap-fit, and the surface of the third connector 31 can be provided with multiple protrusions to increase the friction between the third connector 31 and the clearance opening 1243, thereby improving the connection tightness between the third connector 31 and the clearance opening 1243, and further improving the assembly tightness between the drawer 3 and the support 12.

[0056] In some embodiments of this application, the storage compartment 2 is a freezer compartment, and the refrigerator 100 also includes a refrigerator compartment, an evaporator, and an air duct assembly.
