Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] This application provides a refrigerator to solve the problem of poor drawer pull-out feel. The following description will be provided in conjunction with the accompanying drawings.

[0031] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the refrigerator includes a cabinet liner 1, a fitting 2, and a rolling element 3. The fitting 2 is used to engage with the cabinet liner 1, and the rolling element 3 is rotatably connected to the fitting 2 for rolling contact with the refrigerator drawer.

[0032] It should be noted that the inner liner 1 refers to the structure located inside the refrigerator body that can directly contact the stored items, and is usually made of plastic material. The rolling element 3 may include one or more rollers, balls, or cylinders.

[0033] It is understandable that foam material is usually filled between the drawer liner 1 and the drawer body for insulation. The drawer liner 1 also typically has inwardly protruding ribs to improve its structural strength or to facilitate the installation of other structures. If the rolling element 3 is directly installed on the drawer liner 1, holes need to be drilled and sealed to prevent leakage when the foam liquid is filled between the drawer liner 1 and the drawer body, complicating the production process and increasing costs. This application, however, involves snapping the fitting 2, which includes the rolling element 3, onto the drawer liner 1. This allows for the use of a molded guide rail on the drawer liner 1 with the rolling element 3, reducing production costs while improving the drawer's pull-out feel.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the refrigerator liner 1 is provided with a guide rail groove 111. The end of the guide rail groove 111 facing the refrigerator door is set as an opening. The assembly 2 is located on the side of the guide rail groove 111 facing the refrigerator door and is set to avoid the opening. The assembly 2 has a first mounting surface 21 and a second mounting surface 22 that are arranged opposite to each other. The first mounting surface 21 is engaged with the refrigerator liner 1, and the rolling element 3 is rotatably connected to the second mounting surface 22.

[0035] It should be noted that the guide rail groove 111 is used to guide the drawer to be pulled out. "The accessory 2 is located on the side of the guide rail groove 111 facing the refrigerator door and is set to avoid the opening" means that the installation position of the accessory 2, which is engaged with the inner liner 1, does not affect the drawer to be pulled out along the direction of the drawer to be pulled out along the guide rail groove 111. Furthermore, the rolling element 3 installed on the accessory 2 is located in the direction of the drawer to be pulled out, so that the drawer is in contact with the rolling element 3 for a long time during the process of being pulled out, which is conducive to the smooth pulling of the drawer out of the refrigerator.

[0036] In some embodiments, such as Figure 3 As shown, the first assembly surface 21 is provided with multiple snap-fit ​​slots 211, which snap-fit ​​with the inner box 1.

[0037] It should be noted that the inner liner 1 can be equipped with a protruding structure or a snap-fit ​​structure to achieve snap-fit ​​with the snap-fit ​​groove 211. Generally speaking, the inner liner 1 is provided with an inwardly protruding rib. The snap-fit ​​groove 211 can be set to a matching shape according to the structure of the rib. The installation and fixation of the assembly 2 is achieved by the interference fit between the rib and the groove wall of the snap-fit ​​groove 211.

[0038] It is understandable that the existing structure on the inner box 1 can be used to complete the installation and fixation of the assembly 2, without the need for additional processing on the inner box 1.

[0039] In some embodiments, such as Figure 4 and Figure 5 As shown, the assembly 2 is provided with a buckle 23, and the surface of the box liner 1 facing the first assembly surface 21 is provided with a slot 14, and the buckle 23 is used to engage with the slot 14.

[0040] Understandably, the inner liner 1 typically has multiple inwardly protruding ribs, with adjacent ribs forming a groove 14 for the buckle 23 to engage; or, the inner liner 1 may have an outwardly protruding structure to form the groove 14. The fastener 2 is secured by the engagement between the buckle 23 and the groove 14.

[0041] In some embodiments, such as Figure 3 As shown, the first assembly surface 21 is provided with multiple snap-fit ​​grooves 211, which snap-fit ​​with the inner box 1; the assembly part 2 is provided with a buckle 23, and the surface of the inner box 1 facing the first assembly surface 21 is provided with a slot 14, which is used to snap-fit ​​with the slot 14.

[0042] It should be noted that the inner liner 1 can be equipped with a protruding structure or a snap-fit ​​structure 23 to achieve snap-fit ​​with the snap-fit ​​groove 211. Generally, the inner liner 1 is provided with multiple inwardly protruding ribs. The snap-fit ​​groove 211 can be set to a matching shape according to the structure of the ribs, and the adjacent ribs surround to form a snap-fit ​​groove 14 for the snap-fit ​​23. Alternatively, an outwardly protruding structure can be provided on the inner liner 1 to form a snap-fit ​​groove 14. By using two different snap-fit ​​methods, the assembly 2 can be installed and fixed in different directions, improving the installation stability of the assembly 2.

[0043] In some embodiments, such as Figure 2 and Figure 6 As shown, at least a portion of the housing liner 1 protrudes in the direction from the first mounting surface 21 to the second mounting surface 22 to form a plurality of snap-fit ​​portions 13, and a plurality of snap-fit ​​grooves 211 respectively snap-fit ​​with the plurality of snap-fit ​​portions 13.

[0044] It should be noted that "the direction along the first assembly surface 21 pointing to the second assembly surface 22" refers to the direction from the outside of the refrigerator to the inside. It is understood that by molding the refrigerator liner 1 during production, a snap-fit ​​part 13 for the snap-fit ​​groove 211 can be formed, eliminating the need for opening holes or similar structures on the refrigerator liner 1, thus ensuring the airtightness of the refrigerator liner 1. Furthermore, the raised snap-fit ​​part 13 can improve the structural strength of the refrigerator liner 1 and prevent deformation.

[0045] In some embodiments, such as Figure 2 As shown, multiple snap-fit ​​parts 13 are located on the side of the guide rail groove 111 facing the refrigerator door, and multiple snap-fit ​​grooves 211 are spaced apart along the direction of gravity.

[0046] In some embodiments, such as Figure 3 and Figure 6 As shown, the side of the snap-fit ​​part 13 adjacent to the box liner 1 is recessed inward to form a limiting groove 131. A limiting strip 212 is provided on the side wall of the snap-fit ​​groove 211. The limiting strip 212 is embedded in the limiting groove 131 along the direction in which the snap-fit ​​part 13 is embedded in the snap-fit ​​groove 211.

[0047] It should be noted that the side of the latching part 13 adjacent to the drawer liner 1 refers to the portion of the latching part 13 that is directly connected to the drawer liner 1. Simultaneously, the extending direction of at least one limiting groove 131 is consistent with the drawer's pulling direction, allowing for the assembly of the latching part 13 with the latching groove 211 and the assembly of the limiting strip 212 with the limiting groove 131 in one step. It can be understood that the limiting groove 131 and the limiting strip 212 can prevent the assembly 2 from disengaging in a direction perpendicular to the drawer's pulling direction.

[0048] For example, the limiting strip 212 may be located inside the snap-fit ​​groove 211 or at the opening of the snap-fit ​​groove 211. One or more limiting strips 212 may be provided.

[0049] In some embodiments, such as Figure 3 and Figure 7 As shown, multiple support ribs 213 are provided on the side of the limiting strip 212 opposite to the locking groove 211. When the limiting strip 212 is in an interference fit with the limiting groove 131, the support ribs 213 increase the abutment force between the limiting strip 212 and the groove wall of the limiting groove 131, and avoid increasing the assembly gap between the limiting strip 212 and the groove wall of the limiting groove 131 after deformation due to long-term stress. The position of the support ribs 213 will not interfere with the assembly process of the limiting strip 212 being embedded into the limiting groove 131.

[0050] Specifically, the limiting strip 212 is positioned near the opening of the snap-fit ​​groove 211, and two limiting strips 212 are arranged opposite each other in a direction perpendicular to the insertion of the snap-fit ​​part 13 into the snap-fit ​​groove 211. Support ribs 213 are located on the side of the limiting strip 212 opposite to the snap-fit ​​groove 211 and do not protrude from the end of the snap-fit ​​groove 211. Multiple support ribs 213 are spaced apart along the extension direction of the snap-fit ​​groove 211.

[0051] For example, the fitting 2 can be snapped onto the refrigerator liner 1 in the direction of the inner side of the refrigerator pointing towards the surface where the snap-fit ​​part 13 is located, or it can be snapped onto the drawer in the direction of the drawer pull-out.

[0052] In some embodiments, such as Figure 3 As shown, at least a portion of the inner liner 1 protrudes in the direction from the first mounting surface 21 to the second mounting surface 22 to form a guide portion 11. At least one snap-fit ​​portion 13 is disposed adjacent to and recessed in the guide portion 11. The guide portion 11 is provided with a guide rail groove 111. The side of the guide portion 11 facing the refrigerator door is used to abut against the assembly part 2.

[0053] It should be noted that, as described in the foregoing embodiments, the assembly 2 is located on the side of the guide rail groove 111 facing the refrigerator door and is positioned to avoid the opening. Therefore, in this embodiment, after the assembly 2 engages with the snap-fit ​​part 13, the position of the assembly 2 avoids the opening at one end of the guide rail groove 111. Based on this, by utilizing the guide part 11 protruding from the assembly 2 on the side facing the refrigerator door, the movement of the assembly 2 along the direction in which the drawer is pushed into the refrigerator is restricted, further improving the installation stability of the assembly 2.

[0054] Specifically, when the fitting 2 can be attached to the snap-fit ​​portion 13 adjacent to the guide portion 11, both sides directly connected to the inner box 1 are provided with limiting grooves 131. The two limiting grooves 131 are arranged opposite to each other and extend along the drawer pulling direction. The two limiting grooves 131 can be spaced apart from the inner box 1, or at least a portion of the inner box 1 near the snap-fit ​​portion 13 can be used as the groove wall of the limiting groove 131. In this embodiment, the latter is preferred, which can reduce the difficulty of mold opening of the inner box 1.

[0055] Furthermore, along the direction of the protrusion of the guide portion 11, at least a portion of the guide portion 11 is recessed in the direction of the second mounting surface 22 pointing to the first mounting surface 21 to form a guide groove 111. The bottom of the guide groove 111 protrudes from the liner 1, and one end of the guide groove 111 extends in the direction of pointing to the refrigerator door to form an opening.

[0056] More specifically, the first mounting surface 21 is provided with two vertically arranged snap-fit ​​grooves 211. The lower snap-fit ​​groove 211 is located closer to the guide rail groove 111 and is larger than the upper snap-fit ​​groove 211. Correspondingly, two snap-fit ​​portions 13 are also provided. A latch 23 is located in front of the two snap-fit ​​grooves 211. Along the direction from the first mounting surface 21 to the second mounting surface 22, at least a portion of the cabinet liner 1 protrudes to form a stop portion 12. The stop portion 12 is adjacent to and protrudes from the upper snap-fit ​​portion 13. The side of the stop portion 12 facing the refrigerator door is used to abut against the upper snap-fit ​​groove 211 to restrict the movement of the assembly 2.

[0057] In some embodiments, such as Figure 3 As shown, at least one snap-fit ​​groove 211 penetrates the fitting 2 in a direction away from the refrigerator door, and the snap-fit ​​portion 13 gradually decreases in a direction closer to the refrigerator door. At least one snap-fit ​​groove 211 gradually decreases in a direction closer to the refrigerator door.

[0058] It is understandable that the assembly 2 is assembled onto the inner box 1 along the direction of the drawer being pulled out, and the snap-fit ​​part 13 along its assembly direction can gradually abut against the wall of the snap-fit ​​groove 211.

[0059] Specifically, the latching part 13 gradually decreases in the horizontal direction and along the direction in which the drawer is pulled out of the refrigerator; the latching part 13 also gradually decreases in the direction of gravity and along the direction in which the drawer is pulled out of the refrigerator.

[0060] In some embodiments, such as Figure 4 As shown, the clip 23 is located on the side of the assembly 2 facing away from the refrigerator door. It can be understood that when the assembly 2 is assembled along the direction the drawer is pushed into the refrigerator, the clip 23 immediately engages with the slot 14, completing the installation in one step.

[0061] In some embodiments, such as Figure 5 As shown, the latch 23 includes an extension 231 and a latching part 232 connected to each other. The latching part 232 is used to abut against the latching groove 14, and the extension 231 is connected to the fitting 2 and abuts against the end of the groove of the latching groove 14. When the fitting 2 is removed from the box liner 1, the extension 231 can be pried away from the latching groove 14 while pushing the fitting 2 to pull the latching part 232 out of the latching groove 14.

[0062] In some embodiments, such as Figure 5As shown, the groove wall of the slot 14 facing the refrigerator door is inclined relative to the bottom of the groove 14, which facilitates the insertion of the buckle part 232 into the slot 14.

[0063] In some embodiments, such as Figure 4 As shown, the rolling element 3 includes a roller rotatably connected to the second mounting surface 22.

[0064] In some embodiments, such as Figure 7 As shown, the first assembly surface 21 is provided with a plurality of staggered reinforcing ribs 214.
