Description

Technical Field

[0001] The present application relates to the technical field of low-temperature storage equipment, and in particular to a refrigerator. Background Art

[0002] A refrigerator is an electrical device that can maintain a constant low temperature. It can provide appropriate temperature and humidity conditions for fresh vegetables, fruits, meat and other ingredients, thereby improving the preservation of food.

[0003] The refrigerator has a variety of storage space designs inside, such as drawers, compartments, etc. These designs are not only convenient for users to organize and store food, but also improve the storage efficiency of the refrigerator. Generally, adjacent compartments are separated by shelves, and items can be placed on the shelves.

[0004] Existing refrigerator shelves generally include two structures: integrated and folding. The integrated shelf design has a fixed space between the two shelves. If you need to place a higher object, you can only take out the shelf, which is cumbersome to operate and has low space utilization. The folding shelf includes a support frame and a front layer plate and a rear layer plate placed on the support frame and arranged in front and back. The front layer plate can be folded under the rear layer plate to increase the front shelf space. However, the left and right sides of the front layer plate and the rear layer plate are not fixed to the support frame. After the front layer plate is folded under the rear layer plate, the front of the support frame is not supported by the front layer plate and is easy to deform. If people take out the shelf to clean it when the shelf is folded, it is easy to cause the shelf to fall apart and the layer plate to fall off, posing a safety hazard.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0060] Figure 1 A schematic diagram of the structure of the refrigerator provided in this application.

[0061] See also Figure 1 The present application provides a refrigerator, including a box body 1. The box body 1 may include an outer shell. The outer shell is roughly in the shape of a cuboid.

[0062] The box body 1 may include an inner liner 11. The inner liner 11 is arranged in the outer shell to form a storage space of the refrigerator. The inner liner 11 may be provided with a take-in and take-out opening 111. The take-in and take-out opening 111 may be provided on the side of the inner liner 11 facing the user. To simplify the description, in the following, the side of the inner liner 11 on which the take-in and take-out opening 111 is provided is the front side of the inner liner 11, and the side away from the take-in and take-out opening 111 is the rear side of the inner liner 11.

[0063] The inner tank 11 may be formed with a storage compartment. The storage compartment includes a refrigerator and a freezer to meet different storage needs of users. For example, the refrigerator is suitable for storing vegetables, fruits, beverages, etc., and the freezer is suitable for placing meat, quick-frozen food, etc.

[0064] In order to meet more user needs, the storage room can also include fresh-keeping drawers and variable temperature rooms.

[0065] An installation space is formed between the outer shell and the inner liner 11. The installation space can be used to form a heat-insulating layer for insulating the storage space inside the box 1 from the outside.

[0066] An air duct assembly may be formed in the installation space. The air duct assembly is in communication with the inner container 11. A refrigeration system may be provided in the air duct assembly, and the cold energy generated by the refrigeration system enters the inner container 11 through the air duct assembly to cool the food in the inner container 11.

[0067] The air duct assembly may also include a fan, which is used to accelerate the air flow velocity between the entire air duct assembly and the inner tank 11, thereby accelerating heat exchange and promoting oxygen reduction efficiency.

[0068] The refrigerator may include a door. The door may be hinged to one side of the housing 1 where the access opening is provided, and is used to close the inner container 11 so as to insulate the inner container 11 from the outside.

[0069] Figure 2 A schematic diagram of the structure of the fully unfolded shelf assembly provided in this application.

[0070] See also Figure 1 and Figure 2 The refrigerator may further include a shelf assembly 2. The shelf assembly 2 is connected between two opposite side walls of the inner liner 11. Two opposite side walls of the inner liner 11 are provided with ribs 112. In the present application, the ribs 112 are provided on the left and right walls of the inner liner 11. The ribs 112 on the two side walls are arranged opposite to each other. The ribs 112 extend along the depth direction of the inner liner 11, that is, extend from the access opening 111 to the rear wall of the inner liner 11. The shelf assembly 2 is supported on two opposite ribs 112, thereby forming a shelf space where items can be placed.

[0071] A plurality of ribs 112 are provided on each side wall so that the shelf assembly 2 can be placed at different heights, or a plurality of shelf assemblies 2 can be placed.

[0072] Adjacent ribs 112 are spaced apart along the height direction of the refrigerator, so that shelf spaces for placing items are formed between different shelf assemblies 2.

[0073] The shelf assembly 2 may include a support frame 21. Two support frames 21 are provided. The two support frames 21 are respectively connected to two opposite ribs 112 in a one-to-one correspondence, so that the shelf assembly 2 is supported on the side wall of the inner liner 11.

[0074] The shelf assembly 2 may include a first layer plate 22 and a second layer plate 23. The first layer plate 22 and the second layer plate 23 are arranged side by side between the two support frames 21.

[0075] The first layer 22 may include a glass plate. The second layer 23 may include a glass plate. The glass plate may be a transparent glass plate. The glass plate may also be a translucent glass plate. The lighting in the box 1 can pass through the transparent or translucent glass plate, thereby increasing the brightness in the box 1 and improving the user experience.

[0076] The edge of the glass plate body is wrapped with plastic to increase the reliability of the shelf and prevent the glass plate from falling off due to long-term use. The plastic wrapping and the glass plate body are glued with adhesive to improve the integrity of the appearance of the first layer or the second layer.

[0077] Figure 3 A first visual structural schematic diagram of a shelf assembly provided in the present application in which the first layer of the shelf assembly is folded under the second layer of the shelf assembly. Figure 4 A second visual structural schematic diagram of the shelf assembly provided in the present application in which the first layer of the shelf assembly is folded under the second layer of the shelf assembly.

[0078] like Figure 3 and Figure 4 As shown, a first guide groove 211 may be provided on the support frame 21. The first guide groove 211 extends along the depth direction of the inner liner 11. The first layer plate 22 is connected to the first guide groove 211 on both sides of the support frame 21. The second layer plate 23 is connected to the first guide groove 211 on both sides of the support frame 21.

[0079] The first layer plate 22 can slide forward and backward along the first guide groove 211 to be folded under the second layer plate 23, so that the shelf space where the first layer plate 22 is located when it is unfolded can be opened, so that the shelf space at this location can be connected with the shelf space below. When it is necessary to place items of higher height, the above folding method reduces the restriction of the shelf space on the height of the items placed, thereby improving the applicability of the storage space of the refrigerator.

[0080] Figure 5 This is a first visual structural diagram of the second layer board provided in this application. Figure 6 This is a schematic diagram of the second visual structure of the second layer board provided in this application.

[0081] In some embodiments of the present application, the second layer plate 23 may be provided with an axial body portion 231 protruding toward the support frame 21 , and the axial body portion 231 is penetrated in the support frame 21 , thereby strengthening the connection between the second layer plate 23 and the support frame 21 .

[0082] Figure 7 A schematic diagram of the structure of the support frame provided in this application. Figure 8 This is a schematic diagram of the first visual structure of the second layer board after flipping over provided in this application. Fig. 9 This is a schematic diagram of the second visual structure of the second layer board provided in this application after flipping. Fig.10 A first visual structural schematic diagram of the first layer board and the second layer board provided in the present application after being folded and flipped; Fig.11 This is a second visual structural schematic diagram of the first layer board and the second layer board provided in the present application after being folded and flipped.

[0083] like Figures 7 to 11 As shown, in some implementations of the present application, a through hole 213 may be provided on the support frame 21. The shaft portion 231 is passed through the through hole 213. The shaft portion 231 may be rotatably connected to the support frame 21. The second layer 23 may be turned upward along the shaft portion 231.

[0084] In some embodiments of the present application, when it is necessary to release the shelf space behind the inner container 11, such as Figure 8 and Fig. 9 As shown, when the second layer plate 23 is placed horizontally, the side close to the first layer plate 22 can be flipped upward, thereby opening the shelf space at the rear of the inner container 11.

[0085] When the height, length and width of the items placed in the refrigerator are large, more shelf space needs to be released, such as Fig.10 and Fig.11 As shown, the first layer board 22 can be folded to the bottom of the second layer board 23 first, and then the second layer board 23 can be flipped upward, so that the second layer board 23 drives the first layer board 22 to flip upward, thereby opening up a larger shelf space.

[0086] like Figures 8 to 11 As shown, the shelf assembly 2 may further include a rear layer plate support 25. The rear layer plate support 25 is disposed on a side of the second layer plate 23 away from the access opening 111. Both ends of the rear layer plate support 25 are respectively connected to the rear ends of the two support frames 21. When the second layer plate 23 is flipped upward to the maximum angle, the second layer plate 23 can be tilted against the rear layer plate support 25. At this time, the angle between the second layer plate 23 and the rear layer plate support 25 is less than 90 degrees, so that the second layer plate 23 can be stably supported after flipping.

[0087] Fig.12 This is a schematic diagram of the structure of the rear panel bracket provided in this application.

[0088] like Figure 7 and Fig.12 As shown, the rear end of the support frame 21 may be provided with a connection hole 214. Both ends of the rear layer plate bracket 25 may be provided with mounting posts 251. The mounting posts 251 are rotatably connected to the connection holes 214. The rear layer plate bracket 25 can rotate relative to the support frame 21. The length of the rear layer plate bracket 25 along the height direction is less than its length along the depth direction of the inner liner. By rotating the rear layer plate bracket 25, a gap can be formed between the rear layer plate bracket 25 and the second layer plate 23, so that the second layer plate 23 can be removed from the support frame 21.

[0089] In some embodiments of the present application, Figure 8 As shown, there is a gap between the end of the first guide groove 211 away from the access port 111 and the rear layer plate bracket 25. The length of the gap is not less than the thickness of the second layer plate 23, and can allow the second layer plate 23 to flip upward. When the second layer plate 23 flips upward to the maximum angle, the lower end of the second layer plate 23, that is, the side of the second layer plate 23 away from the access port 111 when the second layer plate 23 is placed horizontally, can abut against the first guide groove 211, thereby limiting the flipping angle of the second layer plate 23, and preventing the second layer plate 23 from flipping too much and colliding with the rear wall of the liner 11. The first guide groove 211 and the rear layer plate bracket 25 limit the second layer plate 23 from the front and rear after it is flipped, respectively, to ensure the stability of the second layer plate 23 after flipping, and also to ensure the effective opening of the shelf space.

[0090] like Figures 2 to 4As shown, in order to further improve the connection stability between the second layer board 23 and the support frame 21, the shelf assembly 2 may include a fixing member 24. The fixing member 24 is connected to the shaft body 231 and abuts against the side of the support frame 21 facing away from the second layer board 23, and can limit the movement of the support frame 21 in the direction away from the second layer board 23, that is, the support frame 21 is fixed on the second layer board 23 in the left and right direction of the box body 1.

[0091] In some embodiments of the present application, the support frame 21 is made of plastic. Since the first layer 22 and the second layer 23 of the glass plate body are heavy, when the shelf assembly 2 needs to be disassembled for cleaning, the support frame 21 made of plastic is easily deformed, especially after the first layer 22 is folded under the second layer 23, the support frame 21 at the corresponding position of the original first layer 22 lacks support. The fixing member 24 fixes the support frame 21 to the second layer 23, which can prevent the first layer 22 and the second layer 23 from falling off due to deformation when the shelf assembly 2 is disassembled from the inner liner 11, thereby reducing the risk of potential safety hazards.

[0092] Fig.13 This is a schematic diagram of the structure of the fixing member provided in this application.

[0093] like Fig.13 As shown, the fixing member 24 may include a connecting portion 241 and a limiting portion 242. An axially extending opening may be provided in the shaft body 231. The connecting portion 241 is inserted into the opening of the shaft body 231. The limiting portion 242 is connected to an end of the connecting portion 241 away from the second layer 23. The limiting portion 242 is provided on the side of the support frame 21 facing away from the second layer 23, and abuts against the support frame 21, so as to limit the support frame 21 between the second layer 23 and the inner side of the limiting portion 242. It can be understood that the outer diameter of the limiting portion 242 is larger than the aperture of the through hole 213, so that the limiting portion 242 can be maintained on the outer side of the support frame 21.

[0094] In some embodiments of the present application, the fixing member 24 may be a screw, which has a simple structure and is easy to assemble and disassemble.

[0096] like Figures 14 to 17As shown, a positioning hole 232 may be provided on the second layer plate 23. A first protrusion 2111 is provided on the lower groove wall of the first guide groove 211. The first protrusion 2111 protrudes toward the second layer plate 23. The first protrusion 2111 is engaged in the positioning hole 232. In this way, the connection stability between the second layer plate 23 and the support frame 21 can be further improved, thereby reducing the possibility of deformation of the support frame 21.

[0097] like Figure 3 and Figure 5 As shown, the bottom of the second layer board 23 may be provided with a second guide slot 233. Both sides of the second layer board 23 connected to the support frame 21 are provided with the second guide slot 233. The second layer board 23 is supported in the first guide slot 211 through the second guide slot 233.

[0098] like Fig.14 and Fig.16 As shown, the positioning hole 232 can be set at the bottom of the second guide groove 233, shortening the distance between the positioning hole 232 and the first protrusion 2111, and improving the connection stability between the second layer board 23 and the support frame 21.

[0099] like Figure 5 As shown, the second guide slot 233 is provided with an opening facing away from the support frame 21. The openings of the second guide slot 233 located on both sides of the second layer plate 23 are arranged opposite to each other. When the first layer plate 22 is folded below the second layer plate 23, the first layer plate 22 is supported by the second guide slot 233.

[0100] like Figure 5 and Fig.10 As shown, the second layer plate 23 may also be provided with a guide slider 234. The guide slider 234 may be provided in the second guide slot 233. The guide slider 234 extends along the extension direction of the second guide slot 233. The guide slider 234 is spaced apart from the upper groove wall of the second guide slot 233, and has a space sufficient to support the first layer plate 22. When the first layer plate 22 is folded below the second layer plate 23, the first layer plate 22 is supported by the guide slider 234. When the first layer plate 22 is stored below the second layer plate 23, the first layer plate 22 slides along the first guide slot 211 to the second guide slot 233. The guide slider 234 is provided in the second guide slot 233, which can avoid the interference between the first layer plate 22 and the first protrusion 2111 engaged in the positioning hole 232 when the first layer plate 22 slides backward, and can reduce the distance between the first layer plate 22 and the second layer plate 23, thereby improving the overall stability of the shelf assembly 2.

[0101] like Figure 7As shown, the bottom of the first guide groove 211 may be formed with a first step portion 2112, a second step portion 2113 and a third step portion 2114. The first step portion 2112, the second step portion 2113 and the third step portion 2114 are distributed in sequence from front to back along the depth direction of the inner tank 11. The heights of the first step portion 2112, the second step portion 2113 and the third step portion 2114 gradually decrease. It is worth noting that the depth direction of the inner tank 11 referred to here refers to the direction of the inner tank 11 access port 111 toward the back plate of the refrigerator. The first layer 22 is supported on the first step portion 2112 and the second step portion 2113. The second layer 23 is supported on the third step portion 2114. There is a height difference between the first step portion 2112 and the second step portion 2113, so that when the first layer plate 22 slides backward, it can obtain a certain gravity acceleration, so that when the user folds the first layer plate 22 under the second layer plate 23, it can be easier to push the first layer plate 22. There is a height difference between the third step portion 2114 and the second step portion 2113, so that when the first layer plate 22 slides backward along the second step portion 2113, it can be stored in the second guide groove 233.

[0102] Fig.18 This is a second visual structural schematic diagram of the shelf assembly provided in the present application when the first layer and the second layer are fully unfolded. Fig.19 for Fig.18 Enlarged view of part A.

[0103] In some embodiments of the present application, a support block 223 may be provided at the bottom of the first layer 22. The support block 223 protrudes toward the second step portion 2113. The support block 223 abuts against the second step portion 2113. The height of the support block 223 is equal to the height difference between the first step portion 2112 and the second step portion 2113. The first layer 22 abuts against the first step portion 2112 on the side close to the access port 111, and the support block 223 offsets the drop between the first step portion 2112 and the second step portion 2113, so that the first layer 22 can be placed horizontally on the support frame 21.

[0104] The support block 223 can be arranged at a position of the second step portion 2113 close to the third step portion 2114. When the first layer plate 22 slides backward, the support block 223 leaves the second step portion 2113. At this time, there is no support of the support block 223 between the first layer plate 22 and the second step portion 2113, so that the first layer plate 22 tilts from front to back, and then more easily enters the second guide groove 233 at the bottom of the second layer plate 23.

[0105] When the second layer plate 23 is placed on the third step portion 2114 , supported by the second guide groove 233 , the upper surface of the second layer plate 23 can be flush with the first layer plate 22 .

[0106] like Figure 7 As shown, in some embodiments of the present application, the first step portion 2112 and the second step portion 2113 may be connected via a first inclined surface 2115. The second step portion 2113 and the third step portion 2114 may be connected via a second inclined surface 2116. The provision of the first inclined surface 2115 and the second inclined surface 2116 can improve the stability of the first layer board 22 sliding backward, and can increase the acceleration of the first layer board 22 sliding backward, thereby improving the power of the first layer board 22 to be stored backward.

[0107] There can be an arcuate transition between the first inclined surface 2115 and the first stepped portion 2112. There can be an arcuate transition between the first inclined surface 2115 and the second inclined surface 2116 and the second stepped portion 2113. There can be an arcuate transition between the second inclined surface 2116 and the third stepped portion 2114. There can be a smooth transition between the first stepped portion 2112 and the first inclined surface 2115, between the second stepped portion 2113 and the first inclined surface 2115 and the second inclined surface 2116, and between the second inclined surface 2116 and the third stepped portion 2114, so as to further improve the stability of the first layer 22 sliding along the first guide groove 211.

[0108] In some embodiments of the present application, the third step portion 2114 is distributed on the side of the shaft portion 231 facing the first layer 22. That is, the third step portion 2114 does not extend to the position on the support frame 21 corresponding to the shaft portion 231, ensuring that the second layer 23 can be turned upward along the shaft portion 231.

[0109] The first protrusion 2111 can be arranged on the side of the third step portion 2114 close to the second step portion 2113. The positioning hole 232 on the second layer plate 23 is arranged on the side close to the first layer plate 22. In this way, when the second layer plate 23 is turned upward, the front side of the second layer plate 23 when it is horizontally unfolded first breaks away from the limit of the first protrusion 2111, and then turns from front to back to open the shelf space on the rear side of the inner liner 11.

[0110] like Figure 5 As shown, in some embodiments of the present application, the shaft body 231 can be arranged on the side of the second layer plate 23 away from the first layer plate 22. In this way, both sides of the second layer plate 23 along the extension direction of the support frame 21 can limit the support frame 21, further reducing the possibility of deformation of the support frame 21.

[0111] In some embodiments of the present application, Figure 5As shown, a blocking block 235 may be provided on the second guide slot 233. The blocking block 235 is provided at one end of the second guide slot 233 away from the access opening 111. The blocking block 235 is respectively connected to the slot walls on both sides of the second guide slot 233 to close the end of the second guide slot 233. When the first layer plate 22 slides to the bottom of the second layer plate 23, the blocking block 235 can limit the rear side of the first layer plate 22. When the second layer plate 23 drives the first layer plate 22 to flip, the blocking block 235 can prevent the first layer plate 22 from falling.

[0112] Fig. 20 for Figure 7 Enlarged view of part D in . Fig.21 This is a schematic diagram of the structure of the first layer board provided in this application. Fig. 22 for Fig.21 Enlarged view of part E in .

[0113] like Figure 20 to Figure 22 As shown, a limiting groove 212 may be provided on the support frame 21. The limiting groove 212 is provided at one end of the support frame 21 away from the second layer plate 23. The limiting groove 212 is connected to one end of the first layer plate 22 close to the access opening 111, and is used to limit the forward movement of the first layer plate 22 to avoid the risk of falling forward when the first layer plate 22 is unfolded.

[0114] The first layer plate 22 may be provided with a second protrusion 221. The second protrusion 221 protrudes toward the access opening 111. The second protrusion 221 is inserted into the limiting groove 212, thereby limiting the forward movement of the first layer plate 22. It can be understood that the second protrusion 221 is provided on both sides of the first layer plate 22 connected to the support frame 21, so that both sides of the first layer plate 22 connected to the support frame 21 can be limited by the limiting groove 212, thereby improving the safety of the shelf assembly 2.

[0115] Fig.23 for Fig.18 Enlarged view of section G in .

[0116] like Fig.18 , Fig. 22 as well as Fig.23 As shown, a limit block 222 may be provided on the first layer 22. The limit block 222 is provided at one end of the first layer 22 away from the second layer 23. The limit block 222 protrudes toward the bottom of the first layer 22 and abuts against the end surface of the support frame 21 facing the access opening 111. The limit block 222 can limit the backward movement of the first layer 22 in the unfolded state, ensuring that when the shelf assembly 2 is fully unfolded, the first layer 22 and the second layer 23 can be stably in a side-by-side state, ensuring the storage safety of items.

[0117] In summary, the present application improves the connection stability between the shaft portion 231 and the support frame 21 by setting an axis portion 231 on the second layer plate 23 to be rotatably connected to the support frame 21, and fixes the shaft portion 231 and the support frame 21 by a fixing member 24, thereby reducing the safety hazard caused by deformation of the support frame 21 due to the heavy weight of the glass plate.

[0118] In addition, the front side of the second layer plate 23 is connected to the first protrusion 2111 on the support frame 21 through the positioning hole 232, which further improves the connection stability between the second layer plate 23 and the support frame 21.

[0119] The first layer plate 22 is provided with a second protrusion 221 and a limit block 222 which respectively cooperate with the support frame 21 , so as to limit the first layer plate 22 at a specific position of the support frame 21 when horizontally unfolded, thereby ensuring the storage safety of articles.

[0120] The second layer plate 23 is provided with a second guide groove 233 capable of accommodating the first layer plate 22, and the second layer plate 23 can be flipped upward along the shaft portion 231, so that the shelf assembly 2 can achieve four different application modes: fully horizontally unfolding, folding the first layer plate 22, flipping the second layer plate 23, and flipping and folding the first layer plate 22 and the second layer plate 23, thereby greatly increasing the possibility of refrigerator storage space and improving the applicability of the refrigerator storage space.

[0121] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and application concept of the present application, and all these changes or substitutions should fall within the protection scope of the claims attached to the present application.
