Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a shelf device and a refrigerator. Background Technology

[0002] With the continuous advancement of science and technology and the rise in economic levels, refrigerators, as a common household appliance, have become increasingly integrated into the daily lives of more and more people. As market demand for refrigerators continues to rise, users are demanding a better user experience. Improving refrigerator production efficiency and maximizing container space utilization are becoming increasingly important. Refrigerators are required to meet various user needs across different scenarios, and their interior design and structure should be simple and bright, without excessive ornamentation. Among these, the refrigerator shelves, as an essential component, significantly impact the partitioning and utilization of the container space. Existing refrigerator shelves fail to meet users' demands for a refined refrigerator experience, and the disassembly and installation of shelves for height adjustment are extremely inconvenient, requiring excessive user effort and greatly hindering human-computer interaction, resulting in a poor user experience. Summary of the Invention

[0003] In order to solve the technical problem of the inconvenience of disassembling and installing refrigerator shelves in the prior art, the present invention proposes a shelf device and a refrigerator.

[0004] The technical solution adopted in this invention is:

[0005] This invention proposes a shelf device, comprising:

[0006] Shelves are located between the opposite side walls of the refrigerator's inner liner.

[0007] The mounting frame is located on the side of the shelf, and the mounting frame is provided with multiple retractable pins on both sides of the shelf. After the pins extend out, they are inserted into the corresponding holes on both sides of the inner wall of the refrigerator to fix the shelf position.

[0008] A telescopic assembly is disposed within the mounting frame. Pressing the pressing part of the telescopic assembly causes the pin to retract, and releasing the pressing part of the telescopic assembly causes the pin to extend.

[0009] Furthermore, the telescopic component includes:

[0010] A telescopic link is provided inside the mounting frame, and a pressing part protruding from the mounting frame is provided on the front side. Pressing the pressing part causes the telescopic link to slide backward inside the mounting frame.

[0011] An elastic element is disposed within the mounting frame and located on the rear side of the telescopic link. When the pressing part is pressed to cause the telescopic link to slide rearward within the mounting frame, the elastic element is compressed. When the pressing part is released, the mounting frame is slid forward by the elastic element until it abuts against the inner wall of the mounting frame.

[0012] The limiting protrusions are provided on the left and right sides of the telescopic connecting rod and are slidably connected to the end of the pin. When the pressing part is pressed, the end of the pin slides from the outward protruding extension part of the limiting protrusion to the inward retraction part, causing the pin to retract inward. When the pressing part is released, the end of the pin slides from the retraction part of the limiting protrusion to the protruding part, causing the pin to extend outward.

[0013] Furthermore, the mounting frame surrounds the front and left and right sides of the shelf, the telescopic link corresponds to the shape of the mounting frame, the mounting frame is provided with parallel side limiting strips in the frame body located on the left and right sides of the shelf, the telescopic link restricts its left and right movement through the limiting strips and the inner edge of the mounting frame, the rear inner wall of the mounting frame is provided with a limiting tube, the elastic element is installed in the limiting tube, and the two ends of the telescopic link extending rearward are inserted into the limiting tube and connected to the elastic element.

[0014] Furthermore, the limiting protrusion and concave block is provided with a T-shaped groove on the side facing the pin, and one end of the pin is provided with a corresponding T-shaped slide rod that is slidably connected to the groove.

[0015] Furthermore, the mounting frame is provided with tube holes on the left and right sides of the shelf for mounting the pin, and the pin extends and retracts along the tube holes while restricting the radial movement of the pin.

[0016] Furthermore, the shelf device also includes: a plurality of shelf fixing members disposed on the outer side walls of opposite sides of the refrigerator liner, the shelf fixing members being vertically disposed along the height direction, and having mounting holes for inserting the pin at different heights, and the refrigerator liner having holes that coincide with the mounting holes.

[0017] Furthermore, the shelf fixing member is elongated and protrudes along its length towards the inner liner of the refrigerator to form fixing grooves facing away from the inner liner. The back of the fixing groove is in contact with the outer wall of the refrigerator, so that the gap between the shelf fixing member and the inner liner of the refrigerator is filled with foaming agent. The mounting hole is provided at the fixing groove.

[0018] Furthermore, the fixing groove is provided with a fixing groove cover that covers the fixing groove. The edge of the fixing groove cover is movably connected to the fixing groove. When the pin extends into the mounting hole, it lifts the fixing groove cover. When the pin retracts, the fixing groove cover covers the mounting hole by its own weight.

[0019] Furthermore, the mounting frame includes an upper frame and a lower frame, which are snap-fitted and fixed around the shelf.

[0020] Furthermore, the front side of the mounting frame is provided with a reserved hole for exposing the pressing part of the telescopic component.

[0021] The present invention also proposes a refrigerator including the aforementioned shelf assembly.

[0022] Compared with existing technologies, this invention, by incorporating a telescopic component and a retractable pin, allows for easy installation. Simply press the pressing part of the telescopic component, the pin retracts, aligns with the hole in the refrigerator liner, and then releasing the pressing part extends the pin into the hole in the refrigerator liner, securing the shelf. This solves the technical problem of the extreme inconvenience of disassembling and installing refrigerator shelves in existing technologies. Furthermore, shelf fixing components with mounting holes are provided on the outer walls of opposite sides of the refrigerator liner, along with fixing covers that enclose the mounting holes. This ensures that cold air from inside the refrigerator does not flow between the refrigerator exterior and the refrigerator liner, while also not occupying internal space within the refrigerator liner.

[0039] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0040] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0041] With the continuous advancement of science and technology and the increasing economic level, refrigerators, as a common household appliance, have become an integral part of the daily lives of more and more people. As market demand for refrigerators continues to rise, users are demanding a better user experience. Improving refrigerator production efficiency and maximizing container space utilization are becoming increasingly important. Refrigerators are required to meet various user needs in different scenarios, and their interior design and structure should be simple and bright, without excessive decoration. Among these components, the shelves within the refrigerator compartment, as an essential part, significantly impact the division and utilization of the container space. Currently, the support and fixation of refrigerator shelves rely on protruding ribs on the inner walls on both sides of the inner liner. This not only occupies valuable refrigerator space but also appears cumbersome and heavy. Furthermore, disassembling and installing shelves to adjust height is extremely inconvenient, requiring excessive user effort and greatly hindering human-computer interaction, resulting in a poor user experience.

[0042] like Figure 1As shown, this invention proposes a shelf device, including: a shelf 102, a mounting frame 105, and a telescopic assembly. The shelf 102 is disposed between opposite side walls of the refrigerator inner liner 201, rationally dividing the space inside the refrigerator to accommodate more items. A mounting frame 105 is provided on the side of the shelf 102, and multiple telescopic pins 104 are provided on both sides of the mounting frame 105. When extended, the pins 104 are inserted into corresponding holes 202 on opposite side walls of the refrigerator inner liner 201 to fix the position of the shelf 102. When the pins 104 are retracted, the shelf 102 can be removed. A telescopic assembly is provided inside the mounting frame 105 on the side of the refrigerator. The telescopic assembly has a pressing part; pressing the telescopic assembly can retract the pins 104; releasing the pressing part can extend the pins 104.

[0043] like Figure 2-5 As shown, in a specific embodiment, the shelf 102 is used to divide the space inside the refrigerator, allowing for the storage of more items by rationally dividing the internal space. The shelf 102 is disposed between the opposite side walls of the refrigerator liner 201. A mounting frame 105 is provided on the side of the shelf 102, and multiple retractable pins 104 are provided on the mounting frames 105 on both sides of the shelf 102 for fixing the shelf 102 to the refrigerator liner 201. Multiple holes 202 are provided on opposite sides of the refrigerator liner 201, and the pins 104 extend out and insert into the corresponding holes 202 on the refrigerator liner 201 to fix the shelf 102. Multiple holes 202 at the same height are used to fix one shelf 102. A telescopic assembly is provided within the mounting frame 105 on the side of the shelf 102. The telescopic assembly is connected to the pin 104, and the telescopic assembly has a pressing part. Pressing the pressing part of the telescopic assembly causes the pin 104 to retract, allowing it to be removed from the hole 202 in the refrigerator inner liner 201. Releasing the pressing part of the telescopic assembly extends the pin 104, which then inserts into the corresponding hole 202 to secure the shelf 102. The telescopic assembly, by driving the pin 104, ensures the shelf 102 is securely fixed. Furthermore, installation and removal only require pressing the pressing part of the telescopic assembly, making it convenient and quick, and improving the user experience.

[0044] Specifically, two pins 104 are provided on the mounting frames 105 on both sides of the shelf 102. Two holes 202 corresponding to the pins 104 are provided on the opposite side walls of the refrigerator liner 201. The holes 202 at the same height on the side walls of the refrigerator liner 201 are used to fix one shelf 102. Pressing the pressing part of the telescopic assembly retracts the pins 104, allowing the shelf 102 to be removed. Releasing the pressing part of the telescopic assembly extends the pins 104, which then insert into the corresponding holes 202 to fix the shelf 102.

[0045] Furthermore, two holes 202 are provided on each of the opposite sides of the refrigerator liner 201. Four holes 202 at the same height on both sides of the refrigerator liner 201 form a group. Multiple groups of holes 202 at different heights can be provided on the refrigerator liner 201. Holes 202 at the same height are used to fix a shelf 102. This allows the shelf 102 to be installed at different heights as needed, making reasonable use of the space inside the refrigerator.

[0046] like Figure 2 As shown, in a further embodiment, a telescopic assembly is provided within the mounting frame 105, which can drive the pin 104 to extend or retract. Specifically, the telescopic assembly includes: a telescopic connecting rod 101, an elastic element 103, and multiple limiting protrusions and recesses 1011. The telescopic connecting rod 101 is disposed within the mounting frame 105 and is limited by the mounting frame 105. A pressing part is provided on the telescopic connecting rod 101 at the front side of the shelf 102. When the pressing part of the telescopic connecting rod 101 is pressed, the telescopic connecting rod 101 can slide rearward within the mounting frame 105. An elastic element 103 is provided inside the mounting frame 105. The elastic element 103 is located on the rear side of the telescopic connecting rod 101, and the other end of the elastic element 103 is in contact with the mounting frame 105. When the pressing part of the telescopic connecting rod 101 is pressed, the telescopic connecting rod 101 slides backward, and the elastic elements 103 at both ends of the telescopic connecting rod 101 retract under pressure. When the pressing part is released, the telescopic connecting rod 101 slides forward towards the mounting frame 105 under the elastic force of the elastic element 103 until it abuts against the inner wall of the mounting frame 105. Limiting protrusions and recesses 1011 are provided on the left and right sides of the telescopic connecting rod 101, and the limiting protrusions and recesses 1011 are slidably connected to the sliding groove. Multiple limiting protrusions and recesses 1011 are respectively provided on both sides of the telescopic connecting rod 101, and each limiting protrusion and recess 1011 is connected to a corresponding pin 104. When the pressing part of the telescopic connecting rod 101 is pressed, the end of the pin 104 slides from the outward protruding top part of the limiting protrusion 1011 to the inward retracting part, causing the pin 104 to retract inward. When the pressing part is released, the end of the pin 104 slides from the retracting part of the limiting protrusion 1011 to the top part, causing the pin 104 to extend outward.

[0047] Specifically, the elastic element 103 can be a spring.

[0048] like Figure 1-6As shown, in a further embodiment, the mounting frame 105 surrounds the front and left and right sides of the shelf 102. The telescopic connecting rod 101, which has the same shape as the shelf 102, is disposed within the mounting frame 105 and also surrounds the front and left and right sides of the shelf 102. The mounting frame has parallel side limiting strips within its frame located on the left and right sides of the shelf. The telescopic connecting rod is disposed between the limiting strips and the inner edge of the mounting frame, restricting the left and right movement of the telescopic connecting rod through the inner edge of the mounting frame and the limiting strips. Limiting tubes 107 are respectively provided on the rear side of the mounting frame 105. Two elastic elements 103 are respectively disposed within the limiting tubes 107 on the rear side of the mounting frame 105. The ends of the telescopic connecting rod 101 extending rearward are inserted into the limiting tubes 107 and connected to the elastic elements 103. When the pressing part of the telescopic connecting rod 101 is pressed, the telescopic connecting rod 101 slides rearward, pressing against the elastic elements 103 disposed within the mounting frame 105. When the pressing part is released, the elastic element 103 returns to its original shape, and the mounting frame 105 slides towards the front side of the mounting frame 105 under the elastic force of the elastic element 103 until it abuts against the inner wall of the front side of the mounting frame 105.

[0049] In a further embodiment, a T-shaped groove is provided on the side of the limiting protrusion 1011 facing the pin 104, and a corresponding T-shaped slide rod is provided at one end of the pin 104. The T-shaped slide rod cooperates with the T-shaped groove to make the pin 104 slide connected to the limiting protrusion 1011.

[0050] In a further embodiment, limiting protrusions and recesses 1011 are provided on both sides of the telescopic connecting rod 101. Each limiting protrusion and recess includes an outwardly protruding extension and an inwardly recessed retractable portion. The extension is arc-shaped and the retractable portion is arc-shaped and inwardly recessed. The extension and retractable portions are smoothly connected, and a T-shaped groove is provided on the side of the extension and retractable portions facing the pin 104 for connection with the pin 104. When the pressing part is pressed, the pin 104 slides from the extension of the limiting protrusion and recess 1011 to the retractable portion, causing the pin 104 to retract inward. When the pressing part is released, the pin 104 slides from the retractable portion of the limiting protrusion and recess 1011 to the extension, causing the pin 104 to extend outward, thus inserting into the hole 202 of the refrigerator inner liner 201 for fixation.

[0051] like Figure 2As shown, in a further embodiment, the mounting frame 105 surrounds the front and left and right sides of the shelf 102, and the telescopic connecting rod 101 is disposed within the mounting frame 105, surrounding the front and left and right sides of the shelf 102. A connecting foot extends from the rear side of the telescopic connecting rod 101, and the connecting foot engages with an elastic element 103 disposed at the end of the limiting tube 107. When the pressing part of the telescopic connecting rod 101 is pressed, the telescopic connecting rod 101 slides backward, pressing against the elastic element 103 disposed on the rear side of the mounting frame 105. When the pressing part is released, the elastic element 103 returns to its original shape, and the mounting frame 105 slides towards the front side of the mounting frame 105 under the elastic force of the elastic element 103 until it abuts against the inner wall of the front side of the mounting frame 105.

[0052] In a further embodiment, the mounting frame 105 is provided with tube holes on the frame on the left and right sides of the shelf for mounting the pin 104. The pin 104 extends and retracts along the tube holes while restricting the radial movement of the pin 104.

[0053] like Figure 7-10 As shown, in another specific embodiment, the shelf device further includes: shelf fixing members 204, a plurality of shelf fixing members 204 are respectively disposed on the outer side walls of opposite sides of the refrigerator inner liner 201, and the shelf fixing members 204 are vertically arranged along the height direction. Mounting holes 203 for inserting pins 104 are provided at different heights on the shelf fixing members 204, and holes 202 on the refrigerator inner liner 201 that coincide with the mounting holes 203 are provided. When installing the shelf 102, the pins 104 pass through the holes 202 on the refrigerator inner liner 201 and the mounting holes 203 on the shelf fixing members 204 for fixation.

[0054] like Figure 8 As shown, in a further embodiment, shelf fixing members 204 are respectively provided on the outer side walls of opposite sides of the refrigerator inner liner 201. The shelf fixing members 204 are vertically arranged and have multiple mounting holes 203 corresponding to the holes 202 of the refrigerator inner liner 201 in the extension direction. The shelf fixing members 204 protrude from the refrigerator inner liner 201 at intervals in the extension direction to form fixing grooves facing away from the refrigerator inner liner 201, and mounting holes 203 are provided on the fixing grooves. The back of each fixing groove is in contact with the outer side wall of the refrigerator inner liner 201, so that the gap between the shelf fixing member 204 and the refrigerator inner liner 201 is filled with foaming agent. The pin 104 passes through the holes 202 on the refrigerator inner liner 201 and the mounting holes 203 of the shelf fixing member 204 and extends into the fixing groove of the shelf fixing member 204 for fixation.

[0055] like Figure 10As shown in a further embodiment, since the mounting hole 203 and the hole 202 of the refrigerator inner liner 201 are exposed, some cold air may enter the mounting hole 203, causing condensation, or impurities may enter the mounting hole 203 or even between the refrigerator outer shell and the refrigerator inner liner 201, preventing the pin 104 from extending into the mounting hole 203. This also affects the aesthetics of the refrigeration equipment. Therefore, a fixing groove cover 205 is provided in the fixing groove of the shelf fixing member 204. The fixing groove cover 205 covers the mounting hole 203 and is movably connected to the mounting groove. Specifically, the upper edge of the fixing groove cover 205 can be movably connected to the mounting groove. When the pin 104 extends into the mounting hole 203, it lifts the fixing groove cover 205; when the pin 104 retracts from the mounting hole 203, the fixing groove cover 205 covers the mounting hole 203 by its own weight.

[0056] like Figure 2 As shown, in a further embodiment, the pressing part of the telescopic link 101 includes a protrusion 1012 extending from the front side of the mounting frame 105. Pressing the protrusion 1012 controls the movement of the telescopic link 101. When the protrusion 1012 is pressed, the telescopic link 101 slides backward, pressing against the elastic member 103 disposed within the mounting frame 105. When the protrusion 1012 is released, the elastic member 103 returns to its original shape, and the mounting frame 105 slides forward under the elastic force of the elastic member 103 until it abuts against the inner wall of the front side of the mounting frame 105.

[0057] like Figure 2 As shown, in a further embodiment, a mounting frame 105 is provided around the shelf 102. The mounting frame 105 is U-shaped, surrounding the front side and both ends of the shelf 102. Specifically, the mounting frame 105 includes an upper frame 1013 and a lower frame 1014, which are snap-fitted and fixed around the shelf 102. Specifically, the lower frame 1014 has the same shape as the upper frame 1013 and is provided with a locking block corresponding to the locking slot of the upper frame 1013. When snapped together, the upper frame 1013 corresponds to the lower frame 1014, and force is applied to snap the locking slot and the locking block together. The connection method of the upper frame 1013 and the lower frame 1014 can also be other connection methods, such as adhesive fixing.

[0058] In a further embodiment, a mounting frame 105 is provided around the shelf 102. The mounting frame 105 specifically includes an upper frame 1013 and a lower frame 1014. Limiting strips 106 are provided on both sides of the lower frame 1014 along the length direction. The telescopic link 101 and the elastic element 103 are locked between the limiting strips 106 and the inner edge of the lower frame 1014 to restrict the telescopic link 101 from moving left and right.

[0059] like Figure 2-3As shown, in a further embodiment, a reserved hole is provided on the front side of the mounting frame 105 to expose the protrusion 1012 of the telescopic component pressing part.

[0060] Preferably, the shelf 102 is made of glass.

[0061] like Figure 7-10 As shown, this invention also proposes a refrigerator using this shelf device. The refrigerator includes a refrigerator liner 201 and a refrigerator outer shell. Shelf fixing members 204 are set on the opposite outer side walls of the refrigerator liner 201, and foam is filled between the refrigerator liner 201 and the refrigerator outer shell. Since the shelf fixing member 204 has a fixing groove, the foam will not cover the fixing groove and affect the insertion of the pin 104 and the opening and closing of the fixing groove cover 205. When installing the shelf 102, press the protrusion 1012 of the extended front mounting frame 105 to extend and retract the pin 104, aligning it with the hole 202 on the refrigerator liner 201. Release the protrusion 1012 to allow the pin 104 to extend into the hole 202 of the refrigerator liner 201 and into the mounting hole 203 of the shelf fixing member 204 to fix the shelf 102. Since the refrigerator liner 201 and the shelf fixing parts 204 are provided with holes 202 and fixing holes of different heights, the shelf 102 can be installed at different heights according to actual usage needs.

[0062] Compared with the prior art, the present invention, by setting a telescopic component and a telescopic pin 104, allows for easy installation. Simply press the pressing part of the telescopic component, and the pin 104 retracts, aligning it with the hole 202 in the refrigerator inner liner 201. Releasing the pressing part extends the pin 104 into the hole 202 in the refrigerator inner liner 201, thus fixing the shelf 102. This solves the technical problem of the extremely inconvenient disassembly and installation of the refrigerator shelf 102 in the prior art. Simultaneously, shelf fixing components 204 with mounting holes 203 are provided on the outer walls of opposite sides of the refrigerator inner liner 201, and fixing groove covers 205 are provided to cover the mounting holes 203, ensuring that cold air inside the refrigerator does not flow between the refrigerator outer shell and the refrigerator inner liner 201, while also not occupying the internal space of the refrigerator inner liner 201.
