Description

Technical Field

[0001] This invention relates to the field of accessories for refrigeration appliances, and more particularly to a shelf and a refrigerator having the shelf. Background Technology

[0002] Existing refrigerators have multi-layer shelves with fixed spacing between them. If the items placed inside are too small, the space between the shelves is wasted. If items are stacked, items at the bottom are inconvenient to access, items inside are forgotten, and there is also a risk of damage to items due to compression from stacking.

[0003] For example, plates containing leftovers occupy part of the space on two adjacent shelves. When multiple plates containing leftovers need to be stored, if they are all laid flat on the shelves, the space utilization of the refrigerator will be low. If the plates containing leftovers are stacked, on the one hand, the bottom of the plates and the leftovers will be contaminated with each other. On the other hand, the plates are unstable when stacked, and there is a risk of the plates tipping over, which will lead to food waste and contamination of the inside of the refrigerator.

[0004] Although some adjustable shelves exist, the existing shelves are adjusted as a whole. They are generally made of glass, are heavy, and the height adjustment is cumbersome, which affects the user experience. Summary of the Invention

[0005] The purpose of this invention is to provide a shelf and a refrigerator having the shelf, thereby improving the space utilization rate inside the refrigerator.

[0006] To achieve the above-mentioned objective, one embodiment of the present invention provides a shelf, comprising: a support; a platform movably connected to the support via a linkage assembly; one of the support and the platform being provided with a guide groove, and one end of the linkage assembly moving along the guide groove to allow the platform and the support to be in a folded or unfolded state; a locking mechanism including a first locking part disposed at the guide groove and a second locking part disposed on the linkage assembly; wherein, when the platform is in a folded state, the first locking part and the second locking part engage to lock the platform.

[0007] As a further improvement of one embodiment of the present invention, the first locking part and the second locking part are engaged to restrict the movement of the end of the connecting rod assembly along the guide groove.

[0008] As a further improvement of one embodiment of the present invention, one of the first locking part and the second locking part is configured as a limiting hole, and the other is configured as a limiting post. When the platform is in a folded state, the limiting post is inserted into the limiting hole.

[0009] As a further improvement of one embodiment of the present invention, the locking mechanism further includes a first corrugated member and a second corrugated member. The first corrugated member is disposed in the guide groove and coaxially arranged with the first locking part. The second corrugated member is disposed in the connecting rod assembly and coaxially arranged with the second locking part. The end of the connecting rod assembly is configured as a roller. The roller is rotatably disposed in the guide groove and moves along the guide groove. The second locking part is fixed to the roller. The first corrugated member has a first corrugated surface, and the second corrugated member has a second corrugated surface. When the platform is in a folded state, the second locking part rotates along the axis of the first locking part so that the first corrugated surface and the second corrugated surface are in a holding state where the crests abut against each other or in a meshing state where the crests and troughs interlock. When in the meshing state, the limiting post and the limiting hole are inserted.

[0010] As a further improvement of one embodiment of the present invention, the linkage assembly is elastic. When the platform is in a folded state, the elastic tendency of the linkage assembly itself drives the second corrugated member to move toward the guide groove so that the first corrugated member and the second corrugated member engage. When the first corrugated member and the second corrugated member are in a resisting state, the linkage assembly has elastic deformation to drive the second corrugated member and the first corrugated member to change from the resisting state to the engaging state.

[0011] As a further improvement of one embodiment of the present invention, the linkage assembly has a second end opposite to the first end, the second end being rotatably connected to one of the platform or the bracket.

[0012] As a further improvement of one embodiment of the present invention, both sides of the platform are connected to a bracket via a connecting rod assembly; each bracket is provided with two guide grooves, the connecting rod assembly includes a first rod and a second rod, the second end of the first rod and the second end of the second rod are respectively rotatably connected to the platform, and the end of the first rod and the end of the second rod are respectively movably disposed with a guide groove.

[0013] As a further improvement of one embodiment of the present invention, the shelf is in two or more sets, and the two or more sets of the shelf are stacked in a vertical direction, with the support of the lower shelf integrally disposed on the platform of the upper shelf.

[0014] As a further improvement of one embodiment of the present invention, the platform moves vertically relative to the bracket, and the folded state of the platform and the bracket is higher than the unfolded state.

[0015] In order to achieve the above-mentioned application objectives, one embodiment of this application also provides a refrigerator, which includes the shelf.

[0016] As a further improvement of one embodiment of the present invention, the refrigerator further includes an inner liner that internally defines a storage space and a support device housed within the storage space; wherein, the support is integrally formed with the inner liner, or the support is integrally formed with the support device, or the support is detachably mounted on the inner liner.

[0017] Compared with the prior art, this application has at least the following technical effects or advantages: one end of the linkage assembly moves along the guide groove, causing the platform to move closer to or further away from the support, so that the platform and the support are in a folded or unfolded state; when the platform and the support are in a folded state, the first locking part and the second locking part engage to lock the platform, and the space occupied by the shelf is reduced; when the platform and the support are in an unfolded state, the platform moves away from the support, and a space is created between the platform and the support, so that the platform can carry materials. Compared with the prior art, the locking structure of this application realizes the quick folding and locking of the shelf without complicated locking operations, improves the folding efficiency, provides a flexible shelf that can be unfolded or stored, and improves the user experience.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0030] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise) and the spatially related descriptive terms used herein will be interpreted accordingly.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first locking part may be referred to as a second locking part, and similarly, a second locking part may be referred to as a first locking part, without departing from the scope of protection of this application.

[0033] This invention provides a shelf, such as Figures 1 to 7 As shown, the device includes: a support 1, a linkage assembly 2, a platform 3, and a locking mechanism 4. The platform 3 is movably connected to the support 1 via the linkage assembly 2. One of the support 1 and the platform 3 is provided with a guide groove 11. One end of the linkage assembly 2 moves along the guide groove 11 to allow the platform 3 and the support 1 to be in a folded or stowed state. The locking mechanism 4 includes a first locking part 41 and a second locking part 42. The first locking part 41 is disposed in the guide groove 11, and the second locking part 42 is disposed on the end of the linkage assembly 2.

[0034] When the platform 3 and the support 1 are folded, the first locking part 41 and the second locking part 42 engage to lock the platform 3, restricting the end of the linkage assembly 2 from moving along the guide groove 11. When the platform 3 and the support 1 are unfolded, the second locking part 42 disengages from the first locking part 41, allowing the platform to carry the item.

[0035] Specifically, the end of the connecting rod assembly 2 is configured as a roller 23, which is rotatably disposed within the guide groove 11 and moves along the guide groove 11. The second locking part 42 is fixed to the roller 23. Preferably, the second locking part 42 is fixed to the end face of the roller 23 facing the bottom wall of the guide groove 11, and the first locking part 41 is fixed to the bottom wall of the guide groove 11. The second locking part 42 moves within the guide groove 11 as the roller 23 rotates, and the roller 23 drives the second locking part 42 to engage or disengage from the first locking part 41.

[0036] like Figure 2 and 3 As shown, one of the first locking part 41 and the second locking part 42 is configured as a limiting hole 411, and the other is configured as a limiting post 421. Specifically, the first locking part 41 is configured as a limiting hole 411, and the second locking part 42 is configured as a limiting post 421. When the platform 3 is in a folded state, the limiting post 421 is inserted into the limiting hole 411. Preferably, the limiting hole 411 is opened in the guide groove 11, and the limiting post 421 is fixed on the end face of the roller 23 facing the guide groove 11. The limiting post 421 rotates together with the roller 23. More preferably, the first locking part 41 includes a bearing post 412, which is fixed in the guide groove 11. The limiting hole 411 is opened in the bearing post 412, and the limiting post 421 is inserted into the limiting hole 411 of the bearing post 412 to restrict the end of the connecting rod assembly 2 from moving along the guide groove 11.

[0037] The locking mechanism 4 also includes a first corrugated member 413 and a second corrugated member 422. When the platform 3 is in a folded state, the first corrugated member 413 and the second corrugated member 422 engage. Specifically, the first corrugated member 413 is fixed in the guide groove 11 and is also fixed on the outer side wall of the support column 412. The second corrugated member 422 is fixed on the end face of the roller 23 facing the guide groove 11. That is, the second corrugated member 422 and the limiting post 421 are both fixed on the same end face of the roller 23. The rotation axis of the limiting post 421 is coaxial with the rotation axis of the second corrugated member 422, and a gap is left between the second corrugated part and the limiting post 421 to provide space for the insertion of the support column 412 and the limiting post 421.

[0038] Specifically, the first corrugated element 413 has a fan-shaped cross-section facing the connecting rod assembly 2, meaning that the first corrugated element 413 has at least an arc-shaped sidewall and a planar sidewall. The first corrugated element 413 is fixed to the bottom wall of the guide groove 11, and the end face of the first corrugated element 413 facing the connecting rod assembly 2 is the first corrugated surface 414. The outline of the first corrugated surface 414 is fan-shaped, and the surface of the first corrugated surface 414 has a corrugated structure. Preferably, the waveform of the first corrugated surface 414 is an S-shaped wave, meaning that the first corrugated surface 414 has a smooth, uneven surface.

[0039] Specifically, the end face of the second corrugated member 422 facing the bracket 1 has a circular outline, which is the second corrugated surface 423. The surface of the second corrugated surface 423 has a corrugated structure corresponding to that of the first corrugated surface 414. The waveform of the second corrugated surface 423 is an S-shaped wave arranged in a circular pattern, that is, the corrugated surface of the second corrugated surface 423 has a smooth and uneven surface. When the first corrugated member 413 and the second corrugated member 422 are engaged, the first corrugated surface 414 and the second corrugated surface 423 are in contact.

[0040] like Figures 4 to 6 As shown, the first corrugated member 413 is fixedly connected to the outer wall of the supporting column 412. In this embodiment, the supporting column 412 and the first corrugated member 413 are integrally formed. Preferably, the crest of the first corrugated member 413 is higher than the end face of the supporting column 412 away from the bracket 1; more preferably, the crest of the first corrugated member 413 is coplanar with the end face of the supporting column 412 away from the bracket 1. The contact position between the first corrugated surface 414 and the planar sidewall of the first corrugated member 413 is the trough of the first corrugated surface 414, which allows the second corrugated member 422 to engage with the first corrugated member 413 along the path from the trough to the crest of the first corrugated surface 414.

[0041] The end face of the limiting post 421 facing away from the roller 23 is higher than the crest of the second corrugated surface 423. More preferably, the portion of the limiting post 421 that is higher than the crest of the second corrugated surface 423 is provided with a straight chamfer to guide the limiting post 421 into the limiting hole 411 of the bearing post 412, thereby avoiding interference between the bearing post 412 and the limiting post 421.

[0042] Specifically, the second locking part 42 rotates along the axis of the first locking part 41 so that the first corrugated surface 414 and the second corrugated surface 423 are in a holding state where the crests abut against each other or in a state where the crests and troughs are engaged. When the first corrugated surface 414 and the second corrugated surface 423 are in an engaged state, the limiting post 421 is inserted into the limiting hole 411.

[0043] The linkage assembly 2 is elastic. When the platform 3 is folded, the elastic tendency of the linkage assembly 2 drives the second corrugated member 422 to move toward the first corrugated member 413 in the guide groove 11, so that the first corrugated member 413 and the second corrugated member 422 are engaged.

[0044] Specifically, during the engagement of the second corrugated member 422 and the first corrugated member 413, the second corrugated member 422 moves along the path from the trough to the crest of the first corrugated surface 414, and the connecting rod assembly 2 undergoes elastic deformation in the direction away from the support 1. The second corrugated member 422 then moves from the crest to the next trough, and the connecting rod assembly 2 releases elastic potential energy, causing the first corrugated surface 414 and the second corrugated surface 423 to come into contact. That is, the first corrugated member 413 and the second corrugated member 422 rotate from the holding state where they are in contact with the crests to the meshing state.

[0045] When the first corrugated part 413 engages with the second corrugated part 422, the limiting post 421 is inserted into the limiting hole 411 to lock the first locking part 41 and the second locking part 42.

[0046] When the first corrugated part 413 disengages from the second corrugated part 422, the limiting post 421 disengages from the limiting hole 411, separating the first locking part 41 and the second locking part 42.

[0047] Specifically, there are two sets of guide grooves 11, both sets of guide grooves 11 are formed on the same side of the bracket 1. Preferably, the guide grooves 11 are waist grooves embedded in the bracket 1, and the two sets of guide grooves 11 are coaxially arranged along the axis of the length direction of the bracket 1. A first locking part 41 is fixedly provided in one of the guide grooves 11; more preferably, a first locking part 41 is fixedly provided in both guide grooves 11, and the two first locking parts 41 are respectively located at opposite ends of the two guide grooves 11. Preferably, the arc-shaped sidewall of the first corrugated member 413 fits against the arc-shaped inner sidewall of the end of the waist groove, and the planar sidewall of the first corrugated member 413 is provided facing the other end of the waist groove. More preferably, the two first locking parts 41 abut against the arc-shaped inner sidewalls of the two waist grooves respectively, that is, the planar sidewalls of the two first locking parts 41 are arranged opposite each other.

[0048] In this embodiment, the inner sidewall of the guide groove 11 is an arc-shaped sidewall, and the guide groove 11 is a waist groove. Both ends of the guide groove 11 are arranged along the length of the support, meaning the sidewalls at the ends of the guide groove 11 are arc-shaped, forming the inner sidewall. In this embodiment, the outer wall of the first corrugated member 413 is an arc-shaped surface corresponding to the inner sidewall, and the outer sidewall of the first corrugated member 413 is in contact with the inner sidewall of the guide groove. The planar sidewall of the first corrugated member 413 faces away from the contacting inner sidewall and is perpendicular to the bottom wall of the guide groove 11.

[0049] The linkage assembly 2 includes a first rod 21 and a second rod 22. The end of the first rod 21 is movably connected to one of the guide grooves 11 via a set of locking mechanisms 4, and the end of the second rod 22 is movably connected to the other guide groove 11 via another set of locking mechanisms 4.

[0050] Specifically, one end of the first rod 21 is rotatably connected to the platform 3, and the other end is rotatably connected to one of the guide grooves 11 and slides within the guide groove 11. One end of the second rod 22 is rotatably connected to the platform 3, and the other end is connected to another guide groove 11 and slides within the guide groove 11.

[0051] like Figure 7As shown, specifically, the support 1 has a frame protrusion 12 protruding from the side facing the connecting rod assembly 2, with a guide groove 11 formed on the side of the frame protrusion 12 facing the connecting rod assembly 2. The platform 3 has a carrier protrusion 31 protruding from the side facing the connecting rod assembly 2, and the frame protrusion 12 and the carrier protrusion 31 protrude by the same distance. One end of the first rod 21 is rotatably connected to the platform 3, and the other end is rotatably connected to a roller 23, and slides through the roller 23 to the guide groove 11 on the frame protrusion 12. One end of the second rod 22 is rotatably connected to the main body of the platform 3, that is, one end of the second rod 22 is rotatably connected to the side of the platform 3 opposite to the recess of the carrier protrusion 31; the other end of the second rod 22 is rotatably connected to another roller 23, and slides through the roller 23 to the guide groove 11 on the main body of the support 1. The frame protrusion 12 and the carrier protrusion 31 are staggered, and the first rod 21 and the second rod 22 are intersected to improve the stability of movement.

[0052] Preferably, the first rod 21 is a straight rod, and it rotates within a vertical plane, meaning both ends of the first rod 21 are on the same vertical plane. The two ends of the second rod 22 are located on the left and right sides of the aforementioned vertical plane. The portion of the second rod 22 near the platform 3 is bent to make way for the first rod 21, preventing interference between the two rods. When the platform 3 approaches the bracket 1, the first rod 21 is located at the bend of the second rod 22. The first rod 21, in conjunction with the second rod 22, keeps the platform 3 horizontal while moving vertically, allowing the platform 3 to have both a folded and unfolded state relative to the bracket 1. Preferably, the folded state of the platform 3 relative to the bracket 1 is higher than the unfolded state.

[0053] In this embodiment, there are two supports 1; a set of connecting rod assemblies 2 are respectively arranged on opposite sides of the platform 3, and one support 1 is connected to the platform 3 through a set of connecting rod assemblies 2. The platform 3 is folded between the two supports 1 or disposed away from the two supports 1 through the two sets of connecting rod assemblies 2.

[0054] like Figure 8 As shown, in another embodiment of this application, there are two sets of shelves, which are stacked vertically, that is, the two shelves are arranged vertically. Specifically, the support 1 of the lower shelf is fixed to the bottom of the platform 3 of the upper shelf. In other embodiments, there are multiple sets of shelves, which are stacked vertically in sequence, and each shelf can be unfolded or folded independently.

[0055] Next, as Figure 9 As shown, one embodiment of this application also provides a refrigerator, which includes a cabinet, a support device 63 and the shelf, the specific structure of which is as described above.

[0056] The box includes a box shell, an inner liner 61 nested inside the box shell, and insulation material filled between the box shell and the inner liner 61 by means of, for example, foaming. The inner liner 61 defines a storage space 62 inside, and a support device 63 is disposed in the storage space 62.

[0057] In this embodiment, the supporting device 63 is a shelf. The inner wall of the inner liner 61 is provided with a sliding groove. The supporting device 63 slides with the inner liner 61 through the sliding groove to separate the storage space 62 of the inner liner 61. The number of supporting devices can be selected according to the actual situation. In this embodiment, three supporting devices 63 are used to separate the storage space 62. The supporting devices 63 are distributed in the vertical direction and are arranged horizontally to support items.

[0058] In this embodiment, the shelf support 1 is fixed to the bottom surface of any supporting device 63. Preferably, the support 1 and the supporting device 63 are integrally formed. In other variations, the shelf support 1 is detachably installed on the inner liner 61. Preferably, the shelf support 1 and the inner liner 61 are integrally formed.

[0059] Taking a set of shelves fixed at the bottom of the supporting device 63 as an example:

[0060] When the platform 3 is in the unfolded state relative to the support 1, the platform 3 and the support device 63 form a space for carrying small items, and the distance between the platform 3 and the adjacent lower support device 63 is reduced, so that the lower support device 63 can also carry space for small items, so that the refrigerator can carry more small items.

[0061] When the platform 3 is folded relative to the support 1, the platform 3 is stored between the two supports 1. The locking mechanism 4 locks the platform 3 to the support 1. The platform 3 is close to the upper support device 63, and the distance between the platform 3 and the lower support device 63 increases, which can store large items.

[0062] When there are multiple layers of shelves arranged vertically between two adjacent support devices 63, the multiple layers of shelves can be expanded or contracted independently, thereby controlling the size and number of spaces between the two support devices 63 to flexibly adapt to the user experience.

[0063] In summary, one embodiment has the following beneficial effects: one end of the linkage assembly 2 moves along the guide groove 11, causing the platform 3 to move closer to or further away from the support 1, so that the platform 3 and the support 1 are in a folded or unfolded state; when the platform 3 and the support 1 are in a folded state, the first locking part 41 and the second locking part 42 engage to lock the platform 3, and the space occupied by the shelf is reduced; when the platform 3 and the support 1 are in an unfolded state, the platform 3 moves away from the support 1, and a space is created between the platform 3 and the support 1, so that the platform 3 can carry materials, providing a flexible shelf that can be unfolded or folded, improving the user experience.

[0064] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0065] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
