[0037] This application provides a refrigerator as an example; please refer to [link to example]. Figures 1-2 , Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. Figure 2 for Figure 1 The exploded view of the refrigerator shown is shown. The refrigerator 100 includes a cabinet liner 110, a drawer 120, a first roller 130, a second roller 140, and a third roller 150.

[0038] The box liner 110 includes two inner sidewalls 111 arranged opposite each other in the left-right direction. The inner sidewalls 111 are provided with a first rib 112 and a second rib 113 extending in the front-back direction. The first rib 112 and the second rib 113 are arranged opposite each other in the vertical direction. The drawer 120 is movably disposed in the box liner 110 and includes two outer sidewalls 121 arranged opposite each other in the left-right direction. The outer sidewalls 121 are provided with a third rib 122 extending in the front-back direction. The first roller 130 is disposed on the inner sidewalls 111. The bottom wall of the third rib 122 is slidably supported on the first roller 130. The second roller 140 and the third roller 150 are disposed on the outer sidewalls 121. The bottom surface of the first rib 112 is slidably supported on the second roller 140. The top wall of the second rib 113 is slidably supported below the third roller 150.

[0039] The inner box 110 forms a forward-facing receiving space, and the drawer 120 is adapted to be slidably disposed within the inner box 110, sliding out or into the receiving space through the opening. The first protruding rib 112 and the second protruding rib 113 can be integrally formed on the inner wall 111 of the inner box 110, for example, by compression molding. The third protruding rib 122 can also be integrally formed on the outer wall 121 of the drawer 120.

[0040] The refrigerator 100 provided in this embodiment has a third rib 122 slidably supported on a first roller 130, allowing the drawer 120 to be slidably connected to the inner liner 110 and suitable for sliding back and forth to be pulled out or slid into the inner liner 110. Furthermore, by adding a second roller 140 and a third roller 150, the first rib 112 is slidably supported above the second roller 140, while the second rib 113 is slidably supported below the third roller 150. This improves the stability of the sliding connection between the drawer 120 and the inner liner 110, enhances the smoothness of the drawer 120's operation, and reduces noise during sliding. Moreover, the elimination of sheet metal guide rails for the sliding connection between the drawer 120 and the inner liner 110 reduces material costs.

[0041] In some embodiments, please refer to Figures 3-4 , Figure 3 for Figure 2 The exploded view shown is an enlarged view of region A. Figure 4 for Figure 2 The exploded view shown is an enlarged view of region B. Along the vertical direction, the second roller 140, the third rib 122, and the third roller 150 are sequentially arranged on the outer side wall 121, while the first rib 112, the first roller 130, and the second rib 113 are sequentially arranged on the inner side wall 111. In practical applications, when the drawer 120 slides back and forth within the inner box 110, the second roller 140, the third rib 122, and the third roller 150 slide back and forth between the first rib 112 and the second rib 113. The first rib 112 and the second rib 113 simultaneously guide and limit the second roller 140, the third rib 122, and the third roller 150. This helps improve the structural stability when the drawer 120 and the inner box 110 are slidably connected.

[0042] It should be noted that, along the vertical direction, the second roller 140, the third rib 122, and the third roller 150 are sequentially arranged on the outer sidewall 121. This indicates that the top surface of the second roller 140, which contacts the first rib 112, needs to be higher than the top surface of the third rib 122, and the bottom surface of the second roller 140 needs to be higher than the bottom surface of the third roller 150. Furthermore, the bottom surface of the third roller 150, which contacts the second rib 113, needs to be lower than the bottom surface of the third rib 122, and the top surface of the third roller 150 needs to be lower than the bottom surface of the second roller 140. Additionally, along the vertical direction, the first rib 112, the first roller 130, and the second rib 113 are sequentially arranged on the inner sidewall 111. This indicates that the top surface of the first roller 130, which contacts the third rib 122, needs to be higher than the top surface of the second rib 113, rather than the second roller 140 as a whole needing to be higher than the third rib 122.

[0043] Preferably, the first roller 130 is disposed in front of the first rib 112 and the second rib 113. This increases the rolling stroke of the first roller 130 on the third rib 122, thereby increasing the distance that the drawer 120 can slide out of the storage space of the drawer liner 110, which improves the convenience for users to store and retrieve items.

[0044] In some embodiments, the front end of the first rib 112 is provided with a chamfer 1121 on the side near the first roller 130; a clearance channel 1122 is formed between the chamfer 1121 and the first roller 130, and the clearance channel 1122 is adapted to allow the second roller 140, the third rib 122, and the third roller 150 to enter and exit the interior of the housing liner 110. For practical applications, please refer to... Figure 5 , Figure 5 This is a schematic diagram of the refrigerator provided in another state according to an embodiment of this application. When the user needs to remove or install the drawer 120 into the inner liner 110, the front end of the drawer 120 can be lifted upwards, causing the drawer 120 to tilt, so that the second roller 140 and the third roller 150 can move to the outside of the inner liner 110 or enter between the first rib 112 and the second rib 113 through the clearance channel 1122.

[0045] In some embodiments, the bottom wall of the third rib 122 is recessed with a limiting groove 1221, and the first roller 130 is adapted to roll in the limiting groove 1221. The limiting groove 1221 is used to limit the rolling stroke of the first roller 130. In this way, the first roller 130 can be prevented from disengaging from the third rib 122, thereby improving the structural stability when the drawer 120 and the box liner 110 are slidably connected.

[0046] In some embodiments, the refrigerator 100 further includes a fourth roller (not shown) detachably mounted on the inner sidewall 111, and the top wall of the third rib 122 is adapted to be slidably supported below the fourth roller. The fourth roller further improves the stability of the sliding connection between the drawer 120 and the inner liner 110, enhances the smoothness of the drawer 120's pull-out, and reduces noise generated by the drawer 120 during sliding. The fourth roller is, for example, detachably mounted at the clearance channel 1122. In practical applications, the user can install the fourth roller on the inner liner 110 after the drawer 120 and the inner liner 110 are slidably connected. This improves the stability of the sliding connection between the drawer 120 and the inner liner 110 and also limits the drawer 120 and the rollers on it, preventing the drawer 120 from easily slipping out through the clearance channel 1122. When a user wants to remove drawer 120 from box liner 110, the fourth roller can be removed from box liner 110 first, so that clearance passage 1122 can allow the second roller 140, the third rib 122 and the third roller 150 to enter and exit the box liner 110.

[0047] In some embodiments, please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of the limiting member installed in the drawer according to an embodiment of this application. The refrigerator 100 also includes a limiting member 160, which is disposed in the limiting groove 1221 near the front end of the refrigerator 100. The limiting member 160 is limited by abutting against the first roller 130 to prevent the first roller 130 from directly impacting the side wall of the limiting groove 1221 and avoiding damage to the drawer 120. The limiting member 160 can be made of a flexible material such as silicone to provide a cushioning effect. Preferably, the limiting wall surface of the limiting member 160 facing the first roller 130 conformally matches the circumferential side wall of the first roller 130. The limiting member 160 and the drawer 120 can be integrally formed.

[0048] In some embodiments, the refrigerator 100 further includes a reinforcing member 170, which is fixed to the refrigerator liner 110, and the first roller 130 is fixedly connected to the reinforcing member 170. By being fixed to the refrigerator liner 110, the reinforcing member 170 strengthens the structural strength at the connection between the first roller 130 and the refrigerator liner 110. Optionally, the refrigerator liner 110 has a mounting hole, through which the mounting shaft of the first roller 130 passes and is fixedly connected to the reinforcing member 170 located on the outer wall of the refrigerator liner 110.

[0049] In some embodiments, drawer 120 includes drawer body 123 and drawer door 124. Drawer door 124 is fixedly connected to the front end of drawer body 123, and drawer body 123 includes an outer side wall 121. Drawer door 124 is adapted to fit against the front end face of drawer liner 110 to close the front opening of drawer liner 110, thereby forming a closed space with the inner wall of drawer liner 110 to prevent the loss of internal cold air. Preferably, the outer wall of drawer body 123 is provided with multiple ribs to improve the structural strength of drawer body 123, while avoiding excessive material costs and excessive weight of drawer 120.

[0050] In some embodiments, a plurality of vent holes 127 are provided on the outer side wall 121. The vent holes 127 are used to allow cold air to circulate, so that the cold air inside the liner 110 can enter the drawer 120 to cool the items inside.

[0051] Optionally, the drawer body 123 also includes a front sidewall 125 near the drawer door 124, the upper edge of the front sidewall 125 extending rearward to form a folded edge 126, and a plurality of ventilation holes 127 provided on the folded edge. The ventilation holes 127 are used to allow cold air to circulate, so that the cold air inside the drawer liner 110 can enter the drawer 120 to cool the items inside.

[0052] The refrigerator 100 provided in this embodiment has a third rib 122 slidably supported on a first roller 130, allowing the drawer 120 to be slidably connected to the inner liner 110 and suitable for sliding back and forth to be pulled out or slid into the inner liner 110. Furthermore, by adding a second roller 140 and a third roller 150, the first rib 112 is slidably supported above the second roller 140, while the second rib 113 is slidably supported below the third roller 150. This improves the stability of the sliding connection between the drawer 120 and the inner liner 110, enhances the smoothness of the drawer 120's operation, and reduces noise during sliding. Moreover, the elimination of sheet metal guide rails for the sliding connection between the drawer 120 and the inner liner 110 reduces material costs.
