Description

Drawer components and refrigerator

[0001] This application is based on and claims priority to Chinese patent applications No. 202411919083.4, No. 202423198023.6, No. 202423201731.0, No. 202423201772.X, and No. 202423201772.X, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of refrigerator technology, for example to a drawer assembly and a refrigerator. Background Technology

[0003] A refrigerator is a refrigeration device that maintains a constant low temperature to keep food or other items at a constant low temperature.

[0004] The related technology discloses a refrigerator drawer assembly, including a drawer body and a slide body. Support plates are provided on both sides of the drawer body, and guide rollers are provided at the rear ends of the support plates. The slide body has a slide groove, and a stop roller is provided at the front end of the slide groove. When the drawer body is pulled outwards, it causes the support plates and rollers to move along the slide groove.

[0005] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0006] When the drawer body is pulled out to the front, in order to prevent it from tipping over, a relatively long support plate needs to be reserved between the guide roller and the stop roller as a support arm, as shown in Figure 8A. This will result in the drawer body being pulled out a shorter distance.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0046] This disclosure provides a refrigerator that includes a drawer assembly.

[0047] In some embodiments, as shown in FIG1, the drawer assembly includes a drawer body 100, a slide body 200, and a support arm 300. The drawer body 100 is movable by pushing and pulling and has a fully extended position. The slide body 200 is located on one side of the drawer body 100 and includes a first slide groove 210. A first end of the support arm 300 is hinged to the side of the drawer body 100, and a second end is provided with a first sliding member located within the first slide groove 210. When the drawer body 100 moves, the support arm 300 drives the first sliding member to move along the first slide groove 210, and at the fully extended position, the support arm 300 provides support for the drawer body 100.

[0048] In this embodiment, the drawer body 100 can be pulled forward or pushed backward, as shown in Figure 1. When the drawer body 100 is pulled forward, it drives the support arm 300 to move, and the movement of the support arm 300 drives the first sliding member to move along the first slide groove 210. Furthermore, when the drawer body 100 moves to its maximum pull-out position, the support arm 300 can provide support for the drawer body 100. Thus, compared to using the support plate 130 as the support arm, using the support arm 300 as the support arm segment allows the drawer body 100 to be pulled forward a longer distance, thereby increasing the travel of the drawer body 100.

[0049] Optionally, as shown in Figure 2, the first slide 210 includes a support section 211 and a storage section 212. The support section 211 extends along the moving direction of the drawer body 100, and its first end faces the front side of the drawer body 100; the first end of the storage section 212 is connected to the second end of the support section 211; and the storage section 212 and the support section 211 form an angle α, where 90°≤α≤180°.

[0050] In this embodiment, the opening of the included angle α faces the front of the drawer body 100. When α is 90°, the storage section 212 is perpendicular to the support section 211. When α is 180°, the storage section 212 is parallel to the support section 211. Since the rear depth of the drawer assembly is limited, by setting a reasonable included angle α, the storage position of the support arm 300 can be changed using the storage section 212, so that the support arm 300 does not extend in the depth direction (α is not 180°), reducing the space occupied on the rear side of the drawer assembly.

[0051] For example, the included angle α can be selected as 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175° or 180°.

[0052] Optionally, as shown in Figure 3A, the storage section 211 extends toward the upper side of the drawer assembly.

[0053] Optionally, as shown in Figure 3B, the storage section 211 extends towards the lower side of the drawer assembly. Here, extending the storage section 211 upwards or downwards can achieve a good storage effect, preventing the support arm 300 from extending in the depth direction.

[0054] Optionally, as shown in Figure 2, the slide body 200 further includes a second slide groove 220. The second slide groove 220 is adjacent to the first slide groove 210 and extends along the moving direction of the drawer body 100; furthermore, a second sliding member and a support plate 130 are provided on the side of the drawer body 100, and both the second sliding member and the support plate 130 are located within the second slide groove 220. When the drawer body 100 moves, the second sliding member and the support plate 130 move along the second slide groove 220.

[0055] In this embodiment, the second slide 220 guides the movement direction of the drawer body 100, and the first slide 210 guides the movement direction of the support arm 300. When the drawer body 100 is pushed or pulled, it moves along the second slide 220 via the second sliding member, and the support plate 130 provides the main support during this movement. Furthermore, after the drawer body 100 has moved to its maximum extended position, the support arm 300 primarily provides support.

[0056] Optionally, as shown in Figures 3A, 3B, and 4, when the included angle α is not 180°, the extending direction of the receiving section 212 intersects the extending direction of the supporting section 211. In this case, the first slide groove 210 and the second slide groove 220 are approximately Y-shaped.

[0057] Optionally, the second slide 220 is arranged adjacent to the support section 211 of the first slide 210, and the support section 211 is located above the second slide 220.

[0058] Optionally, the second end of the storage segment 212 extends upward toward the drawer assembly. Thus, when the drawer body 100 is moved to its maximum pushed-in position, the second end of the storage segment 212 extends upward.

[0059] Optionally, as shown in Figures 3A and 3B, the receiving segment 212 extends along an arc. In this embodiment, the included angle α refers to the angle formed by the line connecting the first and second ends of the receiving segment 212 and the supporting segment 211.

[0060] Optionally, as shown in Figure 4, the receiving segment 212 extends along a straight line.

[0061] Optionally, the storage section 212 and the support section 211 are smoothly connected by a rounded corner section 213. This makes the connection between the two sections of the slide more seamless.

[0062] Optionally, at the maximum pull-out position, the first slider extends beyond the rear of the drawer body 100. This helps to extend the distance the drawer body 100 can be pulled forward.

[0063] Optionally, the first slider includes a first roller 310, and the bending radius of the rounded corner segment 213 is greater than the radius of the first roller 310.

[0064] In this embodiment, when the storage segment 212 extends along an arc, the first end of the storage segment 212 is a rounded corner segment 213. When the storage segment 212 extends along a straight line, the first end of the storage segment 212 is made into a rounded corner segment 213 using a rounding process. In this way, when the drawer body 100 is pushed backward, since the bending radius of the rounded corner segment 213 is larger than the radius of the first roller 310, it can prevent the first roller 310 from hitting the slide groove when passing through the rounded corner segment 213.

[0065] Optionally, a first mounting groove is formed around the wheel body of the first roller 310, and a first anti-collision ring 311 is fitted onto the first mounting groove, as shown in Figure 5. Under the action of the first anti-collision ring 311, the noise of the first roller 310 moving within the first slide groove 210 can be reduced.

[0066] Optionally, the second end of the support arm 300 is provided with a first connecting shaft, and the first roller 310 is rotatably mounted on the first connecting shaft.

[0067] Optionally, at the extreme pull-out position, the first slider is located within the support section 211. This ensures the support effect of the support arm 300.

[0068] Optionally, the drawer body 100 has a fully pushed-in position, and when the drawer body 100 is in the fully pushed-in position, the first slider is located at or near the second end of the storage section 212. This reduces the space occupied by the support arm 300 on the rear side of the drawer assembly.

[0069] Optionally, as shown in Figure 7, when the drawer body 100 is moved to the extreme push-in position, the support arm 300 is perpendicular to or inclined to the direction of extension of the support section 211.

[0070] In this embodiment, at the extreme push-in position, when the angle between the support arm 300 and the forward extension direction of the support segment 211 is acute (as shown in Figure 4), when the drawer body 100 is pulled forward, the first slider needs to move a certain distance towards the second end of the storage segment 212 before moving towards the support segment 211. When the angle between the support arm 300 and the forward extension direction of the support segment 211 is obtuse, the hinge point between the support arm 300 and the drawer body 100 needs to be positioned further forward relative to the first slider, which is not conducive to increasing the travel of the drawer body 100. Therefore, it is preferable that the support arm 300 is perpendicular to the extension direction of the support segment 211, which can both shorten the length of the storage segment 212 and the support arm 300 and ensure the travel of the drawer body 100.

[0071] Optionally, the support arm 300 is provided with a limiting part, which is used to restrict the rotation of the support arm 300 when the first sliding member moves into the support section 211. Under the action of the limiting part, it is beneficial to ensure the supporting effect of the support arm 300.

[0072] Optionally, the drawer body 100 has a mounting lug 110 on its rear side, and the support arm 300 is hinged to the mounting lug 110, as shown in Figure 5. The limiting part includes a limiting surface 111 and a limiting plate 301. The limiting surface 111 is disposed on the mounting lug 110, and the limiting plate 301 is disposed on the support arm 300 and corresponds to the limiting surface 111. When the support arm 300 moves the first sliding member into the support section 211, the limiting plate 301 abuts against the limiting surface 111, thereby limiting the rotation of the support arm 300, as shown in Figure 6.

[0073] In this embodiment, as the support arm 300 moves forward along with the drawer body 100, the support arm 300 rotates simultaneously, and the limiting plate 301 moves synchronously with the support arm 300. When the first sliding member moves into the support section 211, the limiting plate 301 abuts against the limiting surface 111, and the support arm 300 cannot rotate. Thus, when the drawer body 100 moves forward to its maximum pull-out position, as shown in Figures 9 and 10, the support arm 300 provides good support because it cannot rotate.

[0074] Optionally, the limiting part includes a limiting protrusion disposed on the drawer body 100, or the limiting protrusion disposed on the hinge pin 302. When the first sliding member moves into the support section 211, the limiting protrusion abuts against the support arm 300, thereby restricting the rotation of the support arm 300.

[0075] Optionally, the support arm is hinged to the rear side of the drawer body.

[0076] Optionally, as shown in Figure 11, a mounting ear plate 110 is provided on the rear side of the drawer body 100. The mounting ear plate 110 has a through mounting hole, and a bushing 303 is provided in the mounting hole. The first end of the support arm 300 is provided with a hinge pin 302, which is rotatably inserted into the bushing 303.

[0077] In this embodiment, the bushing 303 is made of high-strength POM (polyoxymethylene) material. The hinge pin 302 passes through the bushing 303 and is riveted into the mounting hole. This enhances the connection strength between the support arm 300 and the drawer body 100. Furthermore, when the drawer body 100 is moved to its maximum pull-out position, the deformation of the support arm 300 can be reduced, ensuring the support effect.

[0078] Optionally, the second sliding member includes a second roller 320. The first end of the second slide groove 220 faces the front of the drawer body 100, and the first end is provided with a third roller 330 corresponding to the second roller 320; and when the drawer body 100 moves to its maximum extended position, the second roller 320 is stopped by the third roller 330. At this time, with the rotating arm 300 providing the main support, only a small section of the support plate 130 is located within the second slide groove 220, or the support plate 130 is completely disengaged from the second slide groove 220. Therefore, the drawer body 100 can be pulled forward a longer distance.

[0079] In this embodiment, when the drawer body 100 is pulled forward, it drives the second roller 320 to move synchronously. When the drawer body 100 moves to its maximum extended position, a third roller 330 is used to stop the second roller 320 to prevent the drawer body 100 from dislodging from the second slide rail 220. Furthermore, with the third roller 330 used, the second roller 320 and the third roller 330 roll in contact (as shown in Figure 9), which helps to reduce noise.

[0080] Optionally, the second sliding member includes a second roller 320. The first end of the second slide groove 220 faces the front of the drawer body 100, and the first end is provided with a stop arc surface 221 corresponding to the second roller 320; and when the drawer body 100 moves to its maximum extended position, the second roller 320 is stopped by the stop arc surface 221. At this time, with the support arm 300 providing the main support, only a small section of the support plate 130 is located within the second slide groove 220, or the support plate 130 is completely disengaged from the second slide groove 220. Therefore, the drawer body 100 can be pulled forward a longer distance.

[0081] In this embodiment, when the drawer body 100 is pulled forward, it drives the second roller 320 to move synchronously. When the drawer body 100 moves to its maximum extended position, in order to prevent the drawer body 100 from dislodging from the second slide rail 220, a stop arc surface 221 is used to stop the second roller 320. With the stop arc surface 221 used, the second roller 320 slides in contact with the stop arc surface 221 (as shown in Figure 10). Furthermore, compared with the third roller 330, the stop arc surface 221 requires less space, so it can be positioned closer to the front of the second slide rail 220. Figure 8B shows the maximum travel of the drawer body 100 using the third roller 330, and Figure 8C shows the maximum travel of the drawer body 100 using the stop arc surface 221. It can be seen that using the stop arc surface 221 helps to further increase the travel of the drawer body 100. Here, the second roller 320 and the third roller 330 are respectively equivalent to the guide roller and the stop roller described in the related art.

[0082] Optionally, as shown in Figure 1, a set of support arms 300 and a second sliding member are respectively provided on both sides of the drawer body 100, and a slide body 200 is provided on each side of the drawer body 100. The first sliding member on each support arm 300 moves along the first slide groove 210 on the same side, and the second sliding member moves along the second slide groove 220 on the same side. In this way, the two sets of support arms 300 improve the support effect on the drawer body 100, and the two sets of slide bodies 200 help the drawer body 100 maintain stability during movement.

[0083] In some embodiments, the drawer assembly includes a drawer body 100, a slide rail body 200, and an anti-sway component. The drawer body 100 has a second sliding member on its side. The slide rail body 200 is located on one side of the drawer body 100 and includes a second slide groove 220. The second sliding member is disposed within the second slide groove 220 and is located between a first groove wall 223 and a second groove wall 224 of the second slide groove 220. As shown in FIG12, the anti-sway component includes a first anti-sway member 400 and a second anti-sway member 410; wherein the first anti-sway member 400 is disposed on the first groove wall 223, and the second anti-sway member 410 is disposed on the second groove wall 224, and the second sliding member can be constrained by the first anti-sway member 400 and the second anti-sway member 410 when it sways within the second slide groove 220.

[0084] In this embodiment, the second slide groove 220 extends along the moving direction of the drawer body 100, and the second sliding member moves along the second slide groove 220 when the drawer body 100 moves. Since the second sliding member is located between the first groove wall 223 and the second groove wall 224, when the second sliding member wobbles towards the first groove wall 223, it can be stopped by the first anti-wobbling member 400. When the second sliding member wobbles towards the second groove wall 224, it can be stopped by the second anti-wobbling member 410. In this way, the first anti-wobbling member 400 and the second anti-wobbling member 410 constrain the second sliding member in the opposite direction, effectively reducing the wobbling amplitude when the drawer body 100 moves.

[0085] Optionally, as shown in Figure 13, the second sliding member includes a second roller 320, and a first groove wall 223 and a second groove wall 224 are located on both sides of the second roller 320 in the axial direction. The first groove wall 223 has a slot extending along the second sliding groove 220, and a second connecting shaft is provided on the side of the drawer body 100, and the second connecting shaft passes through the slot and connects to the second roller 320.

[0086] In this embodiment, since the second roller 320 moves back and forth along the second slide groove 220, the two sides of the second roller 320 in the axial direction can be regarded as the left and right sides. Furthermore, when the two slide rail bodies 200 are respectively provided on the left and right sides of the drawer body 100, the first groove wall 223 is the groove wall of the second slide groove 220 near the drawer body 100.

[0087] Optionally, as shown in Figure 12, the first anti-sway component 400 includes two first ribs. The two first ribs are located on both sides of the groove opening, and each first rib is arranged along the extending direction of the second sliding groove 220. In this way, when the second roller 320 sways toward the first groove wall 223, the first ribs can form a stop with the second roller 320.

[0088] Optionally, the two first ribs are positioned near the upper and lower parts of the second roller 320, respectively. This provides a good stopping effect on both the upper and lower parts of the second roller 320 when it wobbles.

[0089] Optionally, as shown in Figure 12, the second anti-sway member 410 includes two second ribs. The two second ribs are disposed on the second groove wall 224 and correspond one-to-one with the two first ribs. Thus, when the second roller 320 sways towards the second groove wall 224, the second ribs can form a stop with the second roller 320. Furthermore, because the positions of the first and second ribs correspond, the force on the second roller 320 is more even when it sways left and right.

[0090] Optionally, as shown in Figure 13, the slide body 200 further includes a first slide groove 210 arranged adjacent to the second slide groove 220. The drawer assembly also includes a support arm 300, the first end of which is hinged to the side of the drawer body 100, and the second end of which is provided with a first sliding member, which is located within the first slide groove 210. The first slide groove 210 includes a support section 211 and a storage section 212. The support section 211 extends along the moving direction of the drawer body 100, and its first end faces the front of the drawer body 100. The first end of the storage section 212 is connected to the second end of the support section 211. In this embodiment, the structure of the first slide groove 210 and the support arm 300 is detailed above and will not be repeated here.

[0091] Optionally, as shown in 12, the support section 211 has opposing third groove walls 214 and fourth groove walls 215, and the first sliding member is located between the third groove wall 214 and the fourth groove wall 215; the anti-sway part further includes a third anti-sway member 420 and a fourth anti-sway member 430; wherein, the third anti-sway member 420 is disposed on the third groove wall 214, and the fourth anti-sway member 430 is disposed on the fourth groove wall 215; and, when the first sliding member sways within the support section 211, it can be constrained by the third anti-sway member 420 and the fourth anti-sway member 430.

[0092] In this embodiment, since the first sliding member is located between the third groove wall 214 and the fourth groove wall 215, when the first sliding member sways towards the third groove wall 214, it can be stopped by the third anti-sway member 420. When the first sliding member sways towards the fourth groove wall 215, it can be stopped by the fourth anti-sway member 430. In this way, the third anti-sway member 420 and the fourth anti-sway member 430 constrain the first sliding member in the relative direction, effectively reducing the swaying amplitude of the first sliding member when it moves along the support section 211.

[0093] Optionally, the first sliding member includes a first roller 310, and a third groove wall 214 and a fourth groove wall 215 are located on both sides of the first roller 310 in the axial direction. The third groove wall 214 has a slot extending along the support section 211, and the second end of the support arm 300 is provided with a first connecting shaft, which passes through the slot and is connected to the first roller 310.

[0094] Optionally, the third anti-sway member 420 includes two third ribs. The two third ribs are located on opposite sides of the groove opening, and each third rib is arranged along the extending direction of the support section 211. Furthermore, the two third ribs are located near the upper and lower parts of the first roller 310, respectively. Thus, when the first roller 310 sways towards the third groove wall 214, the third ribs can form a stop with the first roller 310.

[0095] Optionally, the fourth anti-sway component 430 includes two fourth ribs disposed on the fourth groove wall 215, corresponding one-to-one with the two third ribs. Thus, when the first roller 310 sways towards the fourth groove wall 215, the fourth ribs can act as a stop for the first roller 310. Furthermore, because the third and fourth ribs are positioned correspondingly, the force on the first roller 310 is more evenly distributed when it sways left and right.

[0096] Optionally, the receiving section 212 has a fifth groove wall 216, and the fifth groove wall 216 is connected to the fourth groove wall 215. The anti-sway part also includes a fifth anti-sway member 440, which is disposed on the fifth groove wall 216 and is connected to the fourth anti-sway member 430. In this way, when the first sliding member sways toward the fifth groove wall 216, it can be stopped by the fifth anti-sway member 440.

[0097] In some embodiments, the drawer assembly includes a drawer body 100 and a slide body 200. As shown in FIG14, a second roller 320 is provided on the side of the drawer body 100, and a second anti-collision ring 321 is fitted onto the second roller 320. The slide body 200 is located on one side of the drawer body 100, and the slide body 200 includes a second slide groove 220. The second slide groove 220 extends along the moving direction of the drawer body 100, and the second roller 320 is located within the second slide groove 220. A third roller 330 is provided at the first end of the second slide groove 220, and a third anti-collision ring 331 is fitted onto the third roller 330. Furthermore, when the second roller 320 moves to the first end of the second slide groove 220, it is limited by the third roller 330, and the second anti-collision ring 321 contacts the wheel body of the third roller 330, as shown in FIG15.

[0098] In this embodiment, the second slide 220 extends along the moving direction of the drawer body 100, and the second roller 320 moves along the second slide 220 when the drawer body 100 moves. When the second roller 320 moves to the first end of the second slide 220, it is limited by the third roller 330, thereby preventing the drawer body 100 from coming off the first end of the second slide 220. When the limitation is formed, the wheel bodies of the second roller 320 and the third roller 330 do not collide directly, but the wheel body of the second roller 320 contacts the third anti-collision ring 331, and the wheel body of the third roller 330 contacts the second anti-collision ring 321. In this way, the second anti-collision ring 321 buffers the third roller 330, and the third anti-collision ring 331 buffers the second roller 320, thereby avoiding direct collision and reducing noise.

[0099] Optionally, a second mounting groove is provided around the wheel body of the second roller 320, and a second anti-collision ring 321 is fitted into the second mounting groove, with the outer periphery of the second anti-collision ring 321 extending out of the second mounting groove.

[0100] Optionally, a mounting ear plate 110 is provided on the rear side of the drawer body 100, and the second roller 320 is mounted on the mounting ear plate 110 via a second connecting shaft. In this way, by mounting the second roller 320 on the rear side of the drawer body 100 through the mounting ear plate 110, the travel of the drawer body 100 is increased.

[0101] Optionally, a third mounting groove is provided around the wheel body of the third roller 330, and a third anti-collision ring 331 is fitted into the third mounting groove, with the outer periphery of the third anti-collision ring 331 extending out of the third mounting groove. Here, the portion of the third anti-collision ring 331 extending out of the third mounting groove is used to contact the wheel body of the second roller 320.

[0102] Optionally, as shown in Figure 16, the front of the second slide groove 220 is provided with a roller groove 222, and the third roller 330 is disposed in the roller groove 222 via a third connecting shaft. Here, the roller groove 222 provides installation space for the third roller 330.

[0103] Optionally, the first end of the second slide 220 faces the front of the drawer body 100. When the drawer body 100 is pulled forward to its maximum extended position, the wheel of the second roller 320 contacts the third anti-collision ring 331, and the wheel of the third roller 330 contacts the second anti-collision ring 321. At this time, the second roller 320 and the third roller 330 are in rolling contact, and the second roller 320 is limited by the third roller 330, preventing the drawer from being pulled forward any further.

[0104] Optionally, the drawer body 100 includes a front panel 101, the edges of which protrude to the left and right sides. As shown in Figure 16, a bumper 120 is provided on the front side of the slide body 200, and the bumper 120 corresponds to the edge of the front panel 101. When the drawer body 100 is pushed back to its maximum position, the front panel 101 contacts the bumper 120, thereby creating a cushioning effect and reducing noise.

[0105] Optionally, the front side of the slide body 200 is provided with a mounting hole, and the anti-collision plug 120 is disposed in the mounting hole. This facilitates the installation and replacement of the anti-collision plug 120.

[0106] Optionally, a second roller 320 is provided on each side of the drawer body 100, and a slide rail body 200 is provided on each side of the drawer body 100. Each second roller 320 moves along the second slide groove 220 of the slide rail body 200 on the same side. This helps the drawer body 100 maintain stability during movement.
