Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, for example to a drawer assembly and a refrigerator. BACKGROUND

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and is used to maintain food or other items in a constant low temperature state.

[0003] The related art discloses a drawer assembly of a refrigerator, which comprises a drawer body and a slide body. The drawer body is provided with support plates on both sides, and the rear ends of the support plates are provided with guide rollers. The slide body is provided with a sliding groove, and the front end of the sliding groove is provided with a stop roller. When the drawer body is pulled out, the support plates and the rollers are moved along the sliding groove.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the case where the guide roller and the stop roller are in contact, the wheel bodies of the two rollers are in hard contact, which causes serious wear and loud noise.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. INNOVATION CONTENT

[0007] In order to have a basic understanding of some aspects of the disclosed embodiments, the following is a simple summary. The summary is not a general review, nor is it intended to determine the key / important components or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.

[0008] The embodiments of the present disclosure provide a drawer assembly, which solves the problem of serious wear and loud noise when two rollers are in contact.

[0009] In some embodiments, the drawer assembly comprises:

[0010] a drawer body, the side of which is provided with a second roller, and the second roller is sleeved with a second anti-collision ring;

[0011] a slide body located on one side of the drawer body, comprising a second sliding groove; the second sliding groove extends along the moving direction of the drawer body, and the second roller is located in the second sliding groove; a third roller is arranged at the first end of the second sliding groove, and the third roller is sleeved with a third anti-collision ring;

[0012] Furthermore, when the second roller moves to the first end of the second sliding groove, it is stopped by the third roller, and the second anti-collision ring is in contact with the wheel body of the third roller, and the third anti-collision ring is in contact with the wheel body of the second roller.

[0013] In some embodiments, the refrigerator includes the drawer assembly.

[0014] The drawer assembly and the refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects.

[0015] When the second roller moves to the first end of the second sliding groove, the third roller limits the second roller, thereby preventing the drawer body from being pulled out of the first end of the second sliding groove. When the limiting is formed, the wheel body of the second roller and the wheel body of the third roller do not collide directly, but the wheel body of the second roller contacts the third anti-collision ring, and the wheel body of the third roller contacts the second anti-collision ring. In this way, the third roller is buffered by the second anti-collision ring, and the second roller is buffered by the third anti-collision ring, thereby avoiding direct collision and reducing noise.

[0016] The foregoing general description and the following description are only exemplary and explanatory, and are not used to limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0046] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0047] The present disclosure provides a refrigerator, which includes a drawer assembly.

[0048] In some embodiments, as shown in Figure 1 The drawer assembly includes a drawer body 100, a slide body 200, and a support arm 300. The drawer body 100 is movable in a pulling and pushing manner, and has a limit pull-out position. The slide body 200 is located on one side of the drawer body 100, and includes a first sliding groove 210. The first end of the support arm 300 is hinged to the side of the drawer body 100, and the second end is provided with a first sliding member located in the first sliding groove 210. When the drawer body 100 moves, the first sliding member is driven to move along the first sliding groove 210 by the support arm 300, and at the limit pull-out position, the support arm 300 can support the drawer body 100.

[0049] In the present embodiment, the drawer body 100 can be pulled out forwardly or pushed in rearwardly, and the pulling-out direction and the pushing-in direction are as shown in Figure 1 When the drawer body 100 is pulled out forwardly, the support arm 300 is driven to move, and when the support arm 300 moves, the first sliding member is driven to move along the first sliding groove 210. When the drawer body 100 moves to the limit pull-out position, the support arm 300 can support the drawer body 100. In this way, compared with using the support plate 130 as a support force arm, in the case of using the support arm 300 as a support force arm segment, the drawer body 100 can be pulled out forwardly for a longer distance, thereby increasing the stroke of the drawer body 100.

[0050] Optionally, as shown in Figure 2 The first sliding groove 210 includes a support segment 211 and a receiving segment 212. The support segment 211 extends along the moving direction of the drawer body 100, and the first end thereof faces the front side of the drawer body 100. The first end of the receiving segment 212 is connected to the second end of the support segment 211. The receiving segment 212 and the support segment 211 form an included angle α, and 90°≤α≤180°.

[0051] In the embodiment, the opening of the included angle α is towards the front side of the drawer body 100. In the case of α being 90°, the receiving section 212 is perpendicular to the supporting section 211. In the case of α being 180°, the receiving section 212 is parallel to the supporting section 211. Due to the limited depth of the rear side of the drawer assembly, by setting a reasonable included angle α, the receiving position of the supporting arm 300 can be changed by the receiving section 212, so that the supporting arm 300 does not extend in the depth direction (α is not 180°), and the space of the rear side of the drawer assembly is reduced.

[0052] Exemplarily, 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°.

[0053] Optionally, the receiving section 211 extends towards the upper side of the drawer assembly.

[0054] Optionally, the receiving section 211 extends towards the lower side of the drawer assembly. Here, the receiving section 211 extending upwards or downwards can play a good receiving role, so that the supporting arm 300 does not extend in the depth direction.

[0055] Optionally, as shown in Figure 2 , the slide body 200 further comprises a second sliding groove 220. The second sliding groove 220 is adjacent to the first sliding groove 210 and extends along the moving direction of the drawer body 100; and the side of the drawer body 100 is provided with a second sliding member and a supporting plate 130, and the second sliding member and the supporting plate 130 are located in the second sliding groove 220. The second sliding member and the supporting plate 130 move along the second sliding groove 220 when the drawer body 100 moves.

[0056] In the embodiment, the second sliding groove 220 is used to guide the moving direction of the drawer body 100, and the first sliding groove 210 is used to guide the moving direction of the supporting arm 300. When the drawer body 100 is pushed and pulled, the drawer body 100 moves along the second sliding groove 220 through the second sliding member, and the supporting plate 130 plays a main supporting role in the process of moving. And after the drawer body 100 moves to the limit pull-out position, the supporting arm 300 mainly plays a supporting role.

[0057] Optionally, as shown in Figure 3 and Figure 4 , in the case of the included angle α not being 180°, the extension direction of the receiving section 212 intersects with the extension direction of the supporting section 211. At this time, the whole of the first sliding groove 210 and the second sliding groove 220 is approximately in the shape of “Y”.

[0058] 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.

[0059] 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.

[0060] Optionally, such as Figure 3 As shown, the storage 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 storage segment 212 and the support segment 211.

[0061] Optionally, such as Figure 4 As shown, the storage segment 212 extends along a straight line.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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, such as... Figure 5 As shown. Under the action of the first anti-collision ring 311, the noise of the first roller 310 moving in the first slide groove 210 can be reduced.

[0067] 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.

[0068] 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.

[0069] Optionally, the drawer body 100 has a limit push-in position, and the first slide is located at or close to the second end of the receiving section 212 when the drawer body 100 is located at the limit push-in position. In this way, the rear side space of the drawer assembly occupied by the support arm 300 can be reduced.

[0070] Optionally, as shown in Figure 7 When the drawer body 100 moves to the limit push-in position, the support arm 300 extends perpendicularly or obliquely to the extending direction of the support section 211.

[0071] In the present embodiment, when the angle between the support arm 300 and the extending direction of the support section 211 at the limit push-in position is an acute angle (as shown in Figure 4 When the drawer body 100 is pulled out forward, the first slide needs to move a distance towards the second end of the receiving section 212 and then move towards the support section 211. When the angle between the support arm 300 and the extending direction of the support section 211 is an obtuse angle, the hinge point of the support arm 300 relative to the first slide needs to be arranged more forward, which will not be conducive to increasing the stroke of the drawer body 100. Therefore, it is preferred that the support arm 300 extends perpendicularly to the extending direction of the support section 211, so as to reduce the length of the receiving section 212 and the support arm 300, and to ensure the stroke of the drawer body 100.

[0072] Optionally, a limiting part is arranged on the support arm 300, and the limiting part is used to limit the rotation of the support arm 300 when the first slide moves into the support section 211. Under the action of the limiting part, the support effect of the support arm 300 can be ensured.

[0073] Optionally, a mounting lug 110 is arranged on the rear side of the drawer body 100, 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 arranged on the mounting lug 110, and the limiting plate 301 is arranged on the support arm 300 and corresponds to the limiting surface 111. When the support arm 300 drives the first slide to move into the support section 211, the limiting plate 301 abuts against the limiting surface 111 to limit the rotation of the support arm 300, as shown in Figure 6

[0074] In the present embodiment, when the support arm 300 moves forward with the drawer body 100, the support arm 300 simultaneously rotates and moves, and the limiting plate 301 moves synchronously with the support arm 300. When the first slide moves into the support section 211, the limiting plate 301 abuts against the limiting surface 111, and the support arm 300 cannot rotate. In this way, when the drawer body 100 moves forward to the limit pull-out position, the support arm 300 is perpendicular to the extending direction of the support section 211, as shown in Figure 9 and Figure 10 ​As shown, the support arm 300 can play a better supporting effect due to the inability to rotate.

[0075] Optionally, the limiting part comprises a limiting protrusion, which is arranged on the drawer body 100 or the hinge shaft 302. When the first sliding member moves into the support section 211, the limiting protrusion abuts against the support arm 300, thereby limiting the rotation of the support arm 300.

[0076] Optionally, the support arm is hinged at the rear side of the drawer body.

[0077] Optionally, as shown, Figure 11 As shown, the rear side of the drawer body 100 is provided with a mounting lug plate 110, which is provided with a mounting hole penetrating therethrough, and the mounting hole is provided with a shaft sleeve 303. The first end of the support arm 300 is provided with a hinge shaft 302, which is rotatably arranged in the shaft sleeve 303.

[0078] In the embodiment, the shaft sleeve 303 is made of POM (polyoxymethylene resin) material with high strength. The hinge shaft 302 penetrates through the shaft sleeve 303 and is riveted in the mounting hole. In this way, the connection strength between the support arm 300 and the drawer body 100 is enhanced. Moreover, in the case that the drawer body 100 moves to the limit pull-out position, the deformation of the support arm 300 can be reduced, thereby ensuring the supporting effect.

[0079] Optionally, the second sliding member comprises a second roller 320. The first end of the second sliding groove 220 faces the front side of the drawer body 100, and the first end is provided with a third roller 330 corresponding to the second roller 320; and in the case that the drawer body 100 moves to the limit pull-out position, the second roller 320 is stopped by the third roller 330. At this time, in the case that the rotating arm 300 plays a main supporting role, only a small section of the support plate 130 is located in the second sliding groove 220, or the support plate 130 completely separates from the second sliding groove 220. Therefore, the drawer body 100 can be pulled out a longer distance forward.

[0080] In the embodiment, the drawer body 100 pulls out the second roller 320 synchronously, and when the drawer body 100 moves to the limit pull-out position, the third roller 330 is used to stop the second roller 320 in order to prevent the drawer body 100 from separating from the second sliding groove 220. Moreover, in the case of using the third roller 330, the second roller 320 and the third roller 330 are in rolling contact (as shown in Figure 9

[0081] ​Optionally, the second sliding member comprises a second roller 320. The first end of the second sliding groove 220 is towards the front side of the drawer body 100, and the first end is provided with a stop arc surface 221 corresponding to the second roller 320; and in the case that the drawer body 100 moves to the limit pull-out position, the second roller 320 is stopped by the stop arc surface 221. At this time, in the case that the support arm 300 plays a major supporting role, the support plate 130 is only a small section located in the second sliding groove 220, or the support plate 130 is completely separated from the second sliding groove 220. Therefore, the drawer body 100 can be pulled out forward for a longer distance.

[0082] In the present embodiment, the drawer body 100 pulls out forward to drive the second roller 320 to move synchronously, and when the drawer body 100 moves to the limit pull-out position, in order to prevent the drawer body 100 from being separated from the second sliding groove 220, the stop arc surface 221 is used to stop the second roller 320. In the case of using the stop arc surface 221, the second roller 320 is in sliding contact with the stop arc surface 221 (as shown in Figure 10 ). And the stop arc surface 221 requires less space compared with the third roller 330, so the stop arc surface 221 can be arranged closer to the front side of the second sliding groove 220. Figure 8 (b) the maximum stroke of the third roller 330 for the drawer body 100, Figure 8 (c) the maximum stroke of the stop arc surface 221 for the drawer body 100. It can be seen that the use of the stop arc surface 221 is beneficial to further increase the stroke of the drawer body 100. Here, the second roller 320 and the third roller 330 respectively correspond to the guide roller and the stop roller introduced in the related art.

[0083] Optionally, as shown in Figure 1 , a set of support arms 300 and a second sliding member are arranged on each side of the drawer body 100, and a slide way body 200 is arranged on each side of the drawer body 100. Among them, the first sliding member on each support arm 300 moves along the first sliding groove 210 on the same side, and each second sliding member moves along the second sliding groove 220 on the same side. In this way, the support effect on the drawer body 100 is improved by the two sets of support arms 300, and the drawer body 100 is kept stable during movement by the two sets of slide way bodies 200.

[0084] In some embodiments, the drawer assembly comprises a drawer body 100, a slide way body 200 and a anti-shaking part. Among them, the side of the drawer body 100 is provided with a second sliding member. The slide way body 200 is located on one side of the drawer body 100, and the slide way body 200 comprises a second sliding groove 220. The second sliding member is arranged in the second sliding groove 220 and located between the first groove wall 223 and the second groove wall 224 of the second sliding groove 220. As shown in Figure 12As shown, the anti-shaking part comprises a first anti-shaking member 400 and a second anti-shaking member 410; the first anti-shaking member 400 is arranged on the first slot wall 223, the second anti-shaking member 410 is arranged on the second slot wall 224, and the second sliding member can be restrained by the first anti-shaking member 400 and the second anti-shaking member 410 when shaking in the second sliding slot 220.

[0085] In the embodiment, the second sliding slot 220 extends along the moving direction of the drawer body 100, and the second sliding member moves along the second sliding slot 220 when the drawer body 100 moves. Since the second sliding member is located between the first slot wall 223 and the second slot wall 224, the second sliding member can be stopped by the first anti-shaking member 400 when shaking towards the first slot wall 223. The second sliding member can be stopped by the second anti-shaking member 410 when shaking towards the second slot wall 224. In this way, the first anti-shaking member 400 and the second anti-shaking member 410 restrain the second sliding member in opposite directions, effectively reducing the shaking amplitude when the drawer body 100 moves.

[0086] Optionally, as shown in Figure 13 The second sliding member comprises a second roller 320, and the first slot wall 223 and the second slot wall 224 are located on the two sides of the second roller 320 in the axial direction. The first slot wall 223 is provided with a slot opening extending along the second sliding slot 220, the side of the drawer body 100 is provided with a second connecting shaft, and the second connecting shaft is connected to the second roller 320 through the slot opening.

[0087] In the embodiment, since the second roller 320 moves back and forth along the second sliding slot 220, the two sides of the second roller 320 in the axial direction can be regarded as the left and right sides. Moreover, when the two sliding track bodies 200 are arranged on the left and right sides of the drawer body 100 respectively, the first slot wall 223 is the slot wall of the second sliding slot 220 close to the drawer body 100.

[0088] Optionally, as shown in Figure 12 The first anti-shaking member 400 comprises two first protruding ribs. The two first protruding ribs are located on the two sides of the slot opening respectively, and each first protruding rib is arranged along the extension direction of the second sliding slot 220. In this way, when the second roller 320 shakes towards the first slot wall 223, the first protruding rib can stop the second roller 320.

[0089] Optionally, the two first protruding ribs are close to the upper part and the lower part of the second roller 320 respectively. In this way, the upper part and the lower part of the second roller 320 can be better stopped when the second roller 320 shakes.

[0090] Optionally, as shown in Figure 12As shown, the second anti-shaking part 410 includes two second protrusions. The two second protrusions are arranged on the second groove wall 224 and correspond to the two first protrusions. In this way, when the second roller 320 shakes towards the second groove wall 224, the second protrusions can stop the second roller 320. Moreover, because the positions of the first protrusions and the second protrusions correspond to each other, the force on the second roller 320 when shaking left and right is more uniform.
