Technical Field

[0001] This invention relates to the field of refrigerator technology, and more particularly to a foldable refrigerator shelf structure and a refrigerator. Background Technology

[0002] In a traditional refrigerator structure, multiple guide rails are installed inside the refrigerator liner, and a shelf is installed on each guide rail. The shelf can slide back and forth to be pulled out or inserted into the refrigerator liner.

[0003] However, the height of each guide rail is fixed, and the front and back widths of multiple shelves are uniform, basically occupying the entire front and back space of the box. As a result, when it is necessary to store taller bottles on a shelf on a certain layer, the shelf needs to be manually removed and the position of the shelf adjusted. The operation is complicated, and it is difficult for users to flexibly meet the storage needs of items of different heights.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a foldable refrigerator shelf structure and refrigerator, which addresses the above-mentioned deficiencies of the prior art, and aims to meet the storage needs of items of different heights without disassembling the shelf.

[0006] The technical solution adopted by this invention to solve the technical problem is as follows: A foldable refrigerator shelf structure, comprising: The rear shelf is designed for removable placement on the guide rails inside the refrigerator liner. A guide unit is located at the front end of the rear shelf; The front shelf contacts the guide unit to slide rearward along the guide unit to below the rear shelf to fold relative to the rear shelf, or slides forward along the guide unit to in front of the rear shelf to unfold relative to the rear shelf.

[0007] The foldable refrigerator shelf structure, wherein the guide unit includes: Upper splint; The lower clamping plate is arranged below the upper clamping plate and cooperates with the upper clamping plate to clamp the rear shelf; The guide portion is located below the upper clamping plate and in front of the lower clamping plate; the front end of the guide portion is connected to the upper clamping plate, and the rear end is inclined downward and connected to the lower clamping plate.

[0008] In the foldable refrigerator shelf structure, the front end of the upper clamping plate extends forward beyond the guide portion; when the front shelf is unfolded relative to the rear shelf, the front end of the upper clamping plate contacts the front shelf from the upper surface of the front shelf.

[0010] The aforementioned foldable refrigerator shelf structure further includes: The front interior trim strip is detachably mounted on the front end of the front shelf; The guide rail is provided with a first groove, the opening of the first groove facing upwards; when the front shelf is unfolded relative to the rear shelf, the guide unit is located in the first groove; when the front shelf is folded relative to the rear shelf, the front interior trim strip is located in the first groove.

[0011] The foldable refrigerator shelf structure, wherein when the front shelf is folded relative to the rear shelf, the front end of the front shelf extends forward beyond the guide unit.

[0012] The aforementioned foldable refrigerator shelf structure further includes: A limiting unit is detachably disposed at the rear end of the rear shelf; when the front shelf is folded relative to the rear shelf, the limiting unit contacts the front shelf.

[0013] The foldable refrigerator shelf structure, wherein the limiting unit includes: The rear interior trim strip is fitted onto the rear end of the rear shelf; The limiting part is located at the bottom of the rear interior trim strip and extends vertically downward.

[0019] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0020] This invention provides a foldable refrigerator shelf structure, such as... Figure 1 , Figure 5 and Figure 6 As shown, the foldable refrigerator shelf structure includes: a rear shelf 1, a guide unit 2, and a front shelf 3; the rear shelf 1 is detachably placed on the guide rail 4 of the refrigerator liner 100; as shown... Figure 2 As shown, the guide unit 2 is disposed at the front end of the rear shelf 1; the front shelf 3 contacts the guide unit 2 and slides backward along the guide unit 2 to the bottom of the rear shelf 1 to fold relative to the rear shelf 1, or slides forward along the guide unit 2 to the front of the rear shelf 1 to unfold relative to the rear shelf 1.

[0021] Specifically, the front shelf 3 and the rear shelf 1 are two independent units. A guide unit 2 is provided at the front end of the rear shelf 1. The guide unit 2 contacts the front shelf 3 and guides the movement of the front shelf 3, allowing the front shelf 3 to slide backward under the rear shelf 1. As the front shelf 3 continues to move backward, the overlap area between the front shelf 3 and the rear shelf 1 gradually increases until the overlap area reaches its maximum, and the front shelf 3 can no longer move backward, thus achieving the desired effect. Figure 5 The rear shelf 1 and the front shelf 3 are shown in their folded state.

[0022] When the front shelf 3 is pulled forward relative to the rear shelf 1, under the guidance of the guide unit 2, the overlap area between the front shelf 3 and the rear shelf 1 gradually decreases until the overlap area reaches its minimum, and the front shelf 3 can no longer move forward, thus achieving the desired effect. Figure 6 The diagram shows the unfolded state between the rear shelf 1 and the front shelf 3.

[0023] It is understandable that the overall front-to-back width of the foldable refrigerator shelf structure is minimized when folded, and maximized when unfolded. Furthermore, the inner liner 100 can contain multiple vertically arranged, one-to-one corresponding guide rail sets (each guide rail set includes two left-right arranged guide rails 4) and foldable refrigerator shelf structures (each guide rail set supports one foldable refrigerator shelf structure). Therefore, when a tall item needs to be placed on a foldable refrigerator shelf structure, the front shelf 3 of the upper foldable refrigerator shelf structure can be folded relative to the rear shelf 1, freeing up the space above it to accommodate taller items (such as a 1.5-liter milk container, 32 cm high), without needing to remove the entire foldable refrigerator shelf structure from the inner liner 100. This flexibly addresses temporary storage needs, and is particularly suitable for reconfiguring space when temporarily storing taller food items.

[0024] As can be seen, by setting a guide unit 2 at the front end of the rear shelf 1 and by connecting and sliding the front shelf 3 with the guide unit 2, the user can fold and unfold the rear shelf 1 and the front shelf 3 without disassembling the whole shelf by simply sliding back and forth. This allows for flexible adjustment of the storage space layout according to the height of the stored items. Compared with the prior art, this application simplifies the operation process and improves the user experience.

[0025] One embodiment of this application, such as Figure 2 and Figure 8 As shown, the guide unit 2 includes an upper clamping plate 21, a lower clamping plate 22, and a guide part 23; the lower clamping plate 22 is arranged below the upper clamping plate 21 and cooperates with the upper clamping plate 21 to clamp the rear shelf 1; the guide part 23 is located below the upper clamping plate 21 and in front of the lower clamping plate 22; the front end of the guide part 23 is connected to the upper clamping plate 21, and the rear end of the guide part 23 is inclined downward and connected to the lower clamping plate 22.

[0026] Specifically, the lower clamping plate 22 is located below the upper clamping plate 21 and is arranged opposite to the upper clamping plate 21; the rear end of the lower clamping plate 22 is flush with the rear end of the upper clamping plate 21, and the lower clamping plate 22 and the upper clamping plate 21 are spaced apart to form an accommodating space to accommodate the rear shelf 1; the lower clamping plate 22 is in close contact with the lower surface of the rear shelf 1, and the upper clamping plate 21 is in close contact with the upper surface of the rear shelf 1, so that the upper clamping plate 21 and the lower clamping plate 22 form a clamping of the rear shelf 1.

[0027] The front end of the lower clamping plate 22 is connected to the front end of the upper clamping plate 21 via the guide part 23. That is, the front end of the guide part 23 is connected to the upper clamping plate 21, and the rear end of the guide part 23 is connected to the lower clamping plate 22. The guide part 23 is inclined, and the rear end of the guide part 23 is inclined backward and downward relative to the front end of the guide part 23 to achieve the guiding function. When the front shelf 3 is pushed backward, the rear end of the front shelf 3 contacts the guide part 23 and slides backward along the guide part 23. Under the guidance of the guide part 23, the rear end of the front shelf 3 can slide along the guide part 23 and the lower clamping plate 22 in sequence to the bottom of the rear shelf 1. As the front shelf 3 continues to move backward, the overlap area between the front shelf 3 and the rear shelf 1 gradually increases until the front shelf 3 can no longer move backward, that is, the front shelf 3 and the rear shelf 1 are folded.

[0028] It should be noted that when the front shelf 3 and the rear shelf 1 are in the folded state, the upper surface of the front shelf 3 is in contact with the lower clamping plate 22; the front end of the upper clamping plate 21 extends forward beyond the guide portion 23; when the front shelf 3 is unfolded relative to the rear shelf 1, the front end of the upper clamping plate 21 contacts the front shelf 3 from the upper surface of the front shelf 3.

[0029] With the front shelf 3 and the rear shelf 1 folded, the front shelf 3 is pulled forward and slides forward along the lower clamp 22 until the rear end of the front shelf 3 contacts the lower clamp 22. As the front shelf 3 moves forward, it moves to contact the guide part 23, and the front end of the rear shelf 1 sinks slightly until the rear end of the front shelf 3 moves along the guide part 23 to contact the part of the upper clamp 21 that extends beyond the guide part 23 (i.e., the front end of the upper clamp 21). The sinking of the rear shelf 1 ends, and the front shelf 3 is unfolded relative to the rear shelf 1.

[0030] Understandably, when the front shelf 3 is unfolded relative to the rear shelf 1, the front end of the upper clamp 21 is located above the rear end of the front shelf 3 and contacts the rear end of the front shelf 3, so that the front shelf 3 and the rear shelf 1 can be connected through the guide unit 2 instead of being directly separated, thus ensuring the continuity of the overall shelf structure. Items can also be stored at the connection between the front shelf 3 and the rear shelf 1, without causing items to leak down, and ensuring that the front shelf 3 can move smoothly backward to contact the guide part 23, thereby folding backward.

[0031] In one embodiment of this application, when the current shelf 3 is folded relative to the rear shelf 1, as follows: Figure 5 As shown, the front end of the front shelf 3 extends forward beyond the guide unit 2.

[0032] Specifically, the guide unit 2 is located at the front end of the rear shelf 1, and the front end of the upper clamp 21 in the guide unit 2 extends beyond the rear shelf 1. When the front shelf 3 is folded relative to the rear shelf 1, the front end of the front shelf 3 extends forward beyond the guide unit 2, specifically, the front end of the front shelf 3 extends forward beyond the upper clamp 21, so that the front end of the front shelf 3 can be exposed relative to the upper clamp 21. When the front shelf 3 needs to be unfolded relative to the rear shelf 1, the user can pull the front shelf 3 forward by holding the part of the front end of the front shelf 3 that extends beyond the upper clamp 21, so as to adjust the front shelf 3 to be in an unfolded state relative to the rear shelf 1.

[0033] One embodiment of this application, such as Figure 2 As shown, the foldable refrigerator shelf structure also includes a baffle 24, which is disposed between the upper clamping plate 21 and the lower clamping plate 22 and is arranged vertically; the baffle 24 contacts the front end of the rear shelf 1.

[0034] Specifically, the baffle 24 is located between the upper clamping plate 21 and the lower clamping plate 22, and is connected to the upper clamping plate 21 and the lower clamping plate 22 respectively; the baffle 24 is arranged vertically, the upper end of the baffle 24 is connected to the upper clamping plate 21, and the lower end of the baffle 24 is connected to the front end of the lower clamping plate 22, so that the upper clamping plate 21, the lower clamping plate 22 and the baffle 24 together form a U-shaped receiving space, the opening of the receiving space faces the rear shelf 1, and the receiving space is used to accommodate the rear shelf 1.

[0035] The rear side of the baffle 24 contacts the rear shelf 1, the upper clamp 21 is tightly fitted with the upper surface of the rear shelf 1, and the lower clamp 22 is tightly fitted with the lower surface of the rear shelf 1. Thus, the front end of the rear shelf 1 is clamped by the upper clamp 21, the lower clamp 22 and the baffle 24, so as to achieve stable assembly and positioning of the guide unit 2 at the front end of the rear shelf 1.

[0036] In one embodiment of this application, both the rear shelf 1 and the front shelf 3 are glass shelves; as shown... Figure 3 and Figure 6As shown, the foldable refrigerator shelf structure also includes a front interior trim strip 5, which is detachably mounted on the front end of the front shelf 3. The front interior trim strip 5 is used to protect the front end of the front shelf 3 and prevent the front end of the front shelf 3 from colliding with the inner wall of the refrigerator liner 100, thereby causing damage to the inner wall of the refrigerator liner 100.

[0037] When the front shelf 3 is folded relative to the rear shelf 1, the front interior trim 5 extends forward beyond the upper clamp 21 in the guide unit 2 to ensure that the front interior trim 5 can be exposed in the folded state, so that the user can hold it and change the state of the front shelf 3.

[0038] One embodiment of this application, such as Figure 4 , Figure 5 and Figure 8 As shown, a first groove 41 is provided on the guide rail 4, with the opening of the first groove 41 facing upward; when the current shelf 3 is unfolded relative to the rear shelf 1, the guide unit 2 is located in the first groove 41; when the current shelf 3 is folded relative to the rear shelf 1, the front interior trim 5 is located in the first groove 41.

[0039] Specifically, along the front-to-back direction, the first groove 41 is close to the middle part of the guide rail 4, and the opening of the first groove 41 is arranged facing upwards. Since the guide unit 2 has a certain wrapping around the front end of the rear shelf 1, the upper and lower surfaces of the guide unit 2 are arranged to protrude relative to the upper and lower surfaces of the rear shelf 1, and the upper and lower surfaces of the front interior trim 5 are also arranged to protrude relative to the upper and lower surfaces of the front shelf 3. When the front shelf 3 is folded relative to the rear shelf 1, the guide unit 2 contacts the upper surface of the front shelf 3, and the lower surface of the front interior trim 5 contacts the guide rail 4. Under the superposition of the heights of the guide unit 2 and the front shelf 3, and the superposition of the heights of the front interior trim 5, the front end of the overall shelf structure protrudes more relative to the upper surface of the guide rail 4.

[0040] Therefore, in this application, a first groove 41 is provided on the guide rail 4 to accommodate the front interior trim strip 5, thereby reducing the front height of the overall shelf structure and making the upper surface of the overall shelf structure more horizontal, which is more suitable for storing items and will not cause items to tip over.

[0041] It should be noted that when the current shelf 3 is folded relative to the rear shelf 1, the guide unit 2 contacts the upper surface of the rear shelf 1 and corresponds to the opening of the first groove 41, thereby minimizing the height of the front end of the overall shelf structure so that the upper surface of the overall shelf structure is as close to horizontal as possible.

[0042] When the front shelf 3 is unfolded relative to the rear shelf 1, because the rear shelf 1 is staggered relative to the front shelf 3 and only contacts the front end of the upper clamping plate 21, the maximum stacking height at the connection between the rear shelf 1 and the front shelf 3 is the stacking between the guide unit 2 and the front end of the rear shelf 1, and the stacking between the front shelf 3 and the front end of the upper clamping plate 21 in the guide unit 2. In this application, when the front shelf 3 is unfolded relative to the rear shelf 1, the guide unit 2 is located in the first groove 41, and the rear end of the front shelf 3 and the front end of the rear shelf 1 are both located in the first groove 41, so as to minimize the protrusion height at the connection between the rear shelf 1 and the front shelf 3 and ensure that the upper surface of the overall shelf structure is as horizontal as possible to facilitate the storage of items.

[0043] One embodiment of this application, such as Figure 2 , Figure 5 and Figure 7 As shown, the foldable refrigerator shelf structure also includes a limiting unit 6, which is detachably disposed at the rear end of the rear shelf 1; when the front shelf 3 is folded relative to the rear shelf 1, the limiting unit 6 contacts the front shelf 3. The rear end of the guide rail 4 is provided with a receiving groove 42, the opening of which is arranged upward; the limiting unit 6 is at least partially located within the receiving groove 42.

[0044] Specifically, the receiving slot 42 is located at the rear end of the guide rail 4, and the limiting unit 6 is located at the rear end of the rear shelf 1. The limiting unit 6 is used to cooperate with the receiving slot 42 so that the receiving slot 42 limits the limiting unit 6, thereby limiting the rear shelf 1. When the front shelf 3 is folded relative to the rear shelf 1 and the front shelf 3 is pulled forward to unfold the front shelf 3, the limiting unit 6 is limited by the receiving slot 42 to prevent the rear shelf 1 from moving forward synchronously with the front shelf 3, thus positioning the rear shelf 1 and ensuring that the front shelf 3 can unfold relative to the rear shelf 1.

[0045] like Figure 4 and Figure 5 As shown, a rear blocking part 7 is provided at the rear end of the guide rail 4. The rear blocking part 7 is arranged vertically and is located behind the opening of the receiving groove 42; the rear blocking part 7 is connected to the opening of the receiving groove 42. The rear blocking part 7 is used to contact the limiting unit 6, thereby blocking and limiting the limiting unit 6; when installing the foldable refrigerator shelf structure, the entire shelf structure is placed on the guide rail 4 and pushed backward along the guide rail 4 until the limiting unit 6 contacts the rear blocking part 7, and the entire shelf structure can no longer move backward, thus being installed in place.

[0046] like Figure 4 and Figure 6As shown, the front end of the guide rail 4 is provided with a front blocking part 8, which is arranged vertically; the front end of the guide rail 4 is also provided with a second groove 43, the opening of the second groove 43 is arranged upward; the front blocking part 8 is located on the front side of the second groove 43 and is connected to the opening of the second groove 43. The front blocking part 8 is used to block and limit the front shelf 3; when the front shelf 3 is in the unfolded state relative to the rear shelf 1, the front interior trim 5 is located in the second groove 43 and the front interior trim 5 is in contact with the front blocking part 8.

[0047] With the front shelf 3 folded, pulling it forward causes the front interior trim 5 to contact the upper surface of the guide rail 4 and move forward along the guide rail 4 until the front interior trim 5 contacts the front stop 8 and cannot move forward. At this point, the front shelf 3 is in an unfolded state relative to the rear shelf 1, with the rear end of the front shelf 3 contacting the lower surface of the front end of the upper clamp 21, and the front interior trim 5 located within the second groove 43. Since both the upper and lower surfaces of the front interior trim 5 protrude relative to the front shelf 3, when the front shelf 3 is in an unfolded state relative to the rear shelf 1, the second groove 43 accommodates the front interior trim 5, lowering its height to ensure that the upper surface of the front shelf 3 is horizontal, facilitating the storage of items on the front shelf 3.

[0048] like Figure 2 and Figure 7 As shown, the limiting unit 6 includes a rear interior trim strip 61 and a limiting part 62; the rear interior trim strip 61 is detachably fitted onto the rear end of the rear shelf 1; the limiting part 62 is disposed at the bottom of the rear interior trim strip 61 and extends vertically downward.

[0049] Specifically, the rear interior trim strip 61 has a U-shaped receiving groove with the opening of the U-shaped receiving groove facing forward, and the rear end of the rear shelf 1 is located in the U-shaped receiving groove so as to clamp the rear end of the rear shelf 1 by means of the rear interior trim strip 61. The rear interior trim strip 61 is used to contact the rear blocking part 7, thereby protecting the inner box 100 and the rear shelf 1 and preventing damage to the inner box 100 and the rear shelf 1 due to collision.

[0050] The limiting part 62 is located at the opening of the U-shaped receiving groove and protrudes from the lower surface of the rear interior trim 61; the limiting part 62 extends vertically downward. Whether the front shelf 3 is folded or unfolded relative to the rear shelf 1, a portion of the limiting part 62 is located within the receiving groove 42. When the front shelf 3 is folded relative to the rear shelf 1, the limiting part 62 contacts the rear end of the front shelf 3; when the front shelf 3 is pulled forward, and the front shelf 3 contacts the guide part 23 and slides upward along the guide part 23, the rear shelf 1 sinks, increasing the depth to which the limiting part 62 is inserted into the receiving groove 42. The limiting part 62 is limited by the receiving groove 42, ensuring that the rear shelf 1 does not move forward as the front shelf 3 continues to be pulled forward.

[0051] This application also provides a refrigerator, such as Figure 1 As shown, the refrigerator includes a cabinet 100 and a foldable refrigerator shelf structure as described above; wherein, the cabinet 100 may have multiple vertically arranged and one-to-one corresponding guide rails 4 (each guide rail 4 includes two left and right arranged guide rails 4) and a foldable refrigerator shelf structure (each guide rail 4 corresponds to one foldable refrigerator shelf structure).

[0052] In summary, this application provides a foldable refrigerator shelf structure and a refrigerator, comprising: a rear shelf for detachably placing on a guide rail of the refrigerator liner; a guide unit disposed at the front end of the rear shelf; and a front shelf that contacts the guide unit and is slidable rearward along the guide unit to below the rear shelf to fold relative to the rear shelf, or slides forward along the guide unit to the front of the rear shelf to unfold relative to the rear shelf. This application, by setting the guide unit at the front end of the rear shelf and through the sliding cooperation between the front shelf and the guide unit, allows users to fold and unfold the rear shelf and front shelf without disassembling the entire shelf by simply sliding back and forth. This allows for flexible adjustment of the storage space layout according to the height of the stored items. Compared to existing technologies, this application simplifies the operation process and improves the user experience.
