[0069] The storage device provided in this embodiment can be installed on the side wall of the refrigerator liner to place food or shelves.

[0070] Combination Figure 1-8 As shown, this disclosure provides a storage device, including a housing 10, a first storage section, a second storage section 30, and a third storage section 80.

[0071] The refrigerator body 10 has a receiving space and is open at both the top and bottom. The first storage section includes two oppositely distributed and reversibly movable first storage plates 201 and 202, which overlap the top of the refrigerator body 10. The first and second storage plates 201 and 202, using the refrigerator body 10 as a carrier, move relative to the refrigerator body 10, undergoing various deformations to create multiple load-bearing structures, thus helping to meet diverse load-bearing needs and improving the utilization rate of the refrigerator's internal space. The second storage section 30 is a box-type structure located inside the refrigerator body 10. The third storage section 80 is a box-type structure, at least partially located inside the refrigerator body 10, and detachably connected to the refrigerator body 10. The third storage section 80 is fitted onto the second storage section 30 from bottom to top, and the third storage section 80 and the second storage section 30 enclose an adjustable-volume receiving cavity.

[0072] The second storage section 30 can serve as a basic storage structure, which is a box-like structure, such as a shelf, drawer, or any form of support structure with storage function.

[0073] The third storage unit 80 is designed to be fitted onto the second storage unit 30 from bottom to top. That is, the second storage unit 30 is located above the third storage unit 80, and there can be a certain amount of space or connection between the two.

[0074] The combination of the third storage section 80 and the second storage section 30 creates an adjustable-volume storage cavity. This allows the user to adjust the distance between the third storage section 80 and the second storage section 30 as needed, thereby changing the size of the storage cavity to suit different storage requirements.

[0075] Using the storage device provided in this embodiment, the first storage plate 201 and the second storage plate 202 of the first storage section move relative to the cabinet 10 with the cabinet 10 as the carrier, undergoing various deformations to generate various load-bearing structures, which helps to meet diverse load-bearing needs and thus improve the utilization rate of the refrigerator's internal space. In addition, the adjustable volume design of the accommodating cavity enclosed by the second storage section 30 and the third storage section 80 has flexibility and adjustability, allowing the storage space to be adjusted according to specific needs to further improve the utilization rate of space.

[0076] The cabinet 10 is detachably connected to the side wall of the refrigerator's inner liner 70 and is used to carry the first storage compartment, the second storage compartment 30, and the third storage compartment 80. The first storage compartment is mounted on the top of the cabinet 10, and the second storage compartment 30 and the third storage compartment 80 are placed within the receiving space of the cabinet 10.

[0077] The top of the box 10 has an opening, and the first shelf 201 and the second shelf 202 of the first storage section can be understood as two doors to the top opening of the box 10. The opening and closing of the storage space of the box 10 is achieved by the movement of the first shelf 201 and the second shelf 202. That is, when the first shelf 201 and the second shelf 202 move in opposite directions, the first shelf 201 and the second shelf 202 open the storage space of the box 10. When the first shelf 201 and the second shelf 202 move relative to each other, the first shelf 201 and the second shelf 202 close the storage space of the box 10.

[0078] When the first shelf 201 and the second shelf 202 move, the first shelf 201 and the second shelf 202 slide along the top edge of the box 10.

[0079] Optionally, the second storage section 30 can move up and down within the housing 10 to make the volume of the receiving cavity adjustable.

[0080] The second storage compartment 30 moves upward within the housing 10, which helps users easily retrieve and place food items inside the second storage compartment 30.

[0081] The second storage section 30 moves up and down within the housing 10, and can be used to adjust the storage space of the accommodating cavity according to the size or quantity of different items, thereby making the storage device more flexible in storing food of different sizes and improving space utilization.

[0082] Optionally, the bottom of the second storage section 30 is provided with a plurality of filter holes 301; when the container cavity contains liquid, the liquid in the container cavity can enter the second storage section 30 through the filter holes 301, and the liquid level of the second storage section 30 can be adjusted by the lifting and lowering movement of the second storage section 30.

[0083] When food is placed in the second storage compartment 30, the second storage compartment 30 moves downward, and the liquid in the receiving cavity enters the second storage compartment 30 through the filter hole 301 to clean the food inside the second storage compartment 30. After cleaning, the second storage compartment 30 moves upward, separating the food and liquid inside the second storage compartment 30.

[0084] Users can adjust the lifting distance of the second storage section 30 within the third storage section 80 as needed, thereby adjusting the flow of liquid into the second storage section 30 through the filter hole 301 and flexibly controlling the liquid level within the second storage section 30.

[0085] Optionally, the bottom of the third storage section 80 is provided with a drain outlet 802 to drain the liquid in the replacement chamber.

[0086] Optionally, the third storage section 80 is fixedly connected to the housing 10. The second storage section 30 moves up and down relative to the housing 10 and the third storage section 80.

[0087] Optionally, the bottom side wall of the housing 10 is provided with an anti-detachment part 103, and the side wall of the third storage part 80 is provided with an anti-detachment mating part 801. The anti-detachment part 103 and the anti-detachment mating part 801 are connected to connect the third storage part 80 with the housing 10.

[0088] The connection between the anti-detachment part 103 and the anti-detachment mating part 801 not only helps to improve the stability and firmness of the connection between the third storage part 80 and the box 10, but also makes it easier to install and disassemble the third storage part 80, facilitating maintenance and cleaning.

[0089] The connection between the anti-detachment part 103 and the anti-detachment mating part 801 can be considered as a mechanical or physical connection method (such as buckle, screw, magnetic adsorption, etc.). The anti-detachment part 103 and the anti-detachment mating part 801 are connected to each other, thereby fixing the third storage part 80 to the box body 10.

[0090] For example, the anti-detachment part 103 is a hook or cantilever, and the anti-detachment mating part 801 includes a cantilever structure of the third storage part 80 and a ring sleeve fitted onto the cantilever structure. The ring sleeve is not only fitted onto the cantilever structure, but also simultaneously fitted onto the anti-detachment part 103 on the bottom side wall of the box 10. This achieves the connection and fixation between the third storage part 80 and the box 10. It should be noted that the number and position of the anti-detachment part 103 and the anti-detachment mating part 801 are determined according to the size and weight of the third storage part 80 and the box 10, and are not specifically limited here.

[0091] Optionally, the storage device further includes a drive device disposed in the housing 10 and connected to the first storage part and the second storage part 30, for driving the first storage part to translate and the second storage part 30 to rise and fall; when the second storage part 30 rises to the top of the housing 10, the first storage plate 201 and the second storage plate 202 move in opposite directions to open the top opening of the housing 10 and expose the second storage part 30.

[0092] The second storage section 30 moves up and down within the housing 10, facilitating the user's access to items placed within it. The first and second storage panels 201 and 202 move in opposite directions, opening the housing 10's accommodating space. At this time, the second storage section 30 can gradually rise to the top of the housing 10, again facilitating user access to items. Furthermore, when the second storage section 30 rises to the top of the housing 10, and its top is flush with the tops of the first and second storage panels 201 and 202, the top of the storage device expands from a two-section to a three-section design. This increases the load-bearing area of ​​the top of the storage device, allowing for the placement of more food items. When the top of the storage device is in a two-section configuration, the storage area is smaller than when the top of the storage device is in a three-section configuration.

[0093] For example, if a refrigerator needs to simultaneously store a horizontally elongated item A and a vertically tall item B, the existing shelf structure cannot accommodate both items A and B at the same time. Because item B requires a certain amount of height space, the shelf needs to be removed, making it impossible to store item A. Using the storage device provided in this embodiment, two storage devices are installed on opposite sides of the refrigerator interior. Depending on the width of item A, a three-section or two-section structure is selected. The two storage devices support both ends of item A, thus enabling its placement. Item A no longer needs a shelf; removing the shelf integrates the top and bottom spaces, freeing up height space to meet the storage requirements of item B.

[0094] The first and second storage sections 30 use the cabinet 10 as a carrier and can move relative to the cabinet 10, undergoing various deformations to generate various load-bearing structures, thereby meeting diverse load-bearing requirements and improving the utilization rate of the refrigerator's internal space.

[0095] The first storage section is located on the top of the box 10, and the second storage section 30 is located inside the box 10. Under the action of the driving device, the first storage plate 201 and the second storage plate 202 move horizontally, and the second storage section 30 moves vertically under the action of the driving device.

[0096] The drive unit is mounted on the side wall of the housing 10 as a carrier to achieve the purpose of fixed installation.

[0097] The drive device can be electrically driven to move the first and second storage sections 30, or it can be manually driven to move the first and second storage sections 30.

[0098] Optionally, the driving device includes: a first transmission assembly 40 disposed in the housing 10 and connected to the first shelf 201 and the second shelf 30; and a second transmission assembly 50 disposed in the housing 10 and connected to the second shelf 202 and the second shelf 30; wherein the first transmission assembly 40 and the second transmission assembly 50 are connected in a transmission manner to make the first shelf 201, the second shelf 202 and the second shelf 30 move synchronously.

[0099] The driving device drives the first shelf 201 to move through the first transmission component 40 and drives the second shelf 202 to move through the second transmission component 50. The first transmission component 40 and the second transmission component 50 are connected to each other, thereby realizing the synchronous movement of the first shelf 201 and the second shelf 202.

[0100] The first transmission assembly 40 is connected to the second storage part 30, and the second transmission assembly 50 is also connected to the second storage part 30. The first transmission assembly 40 and the second transmission assembly 50 are connected in a transmission manner. In this way, when driving the second storage part 30 to move up and down, the force on any one set of transmission assemblies is reduced, which helps to improve the stability of the second storage part 30 during the movement.

[0101] In addition, the first transmission component 40 drives the first shelf 201 and the second shelf 30, and the second transmission component 50 drives the second shelf 202 and the second shelf 30. The first transmission component 40 and the second transmission component 50 are connected by transmission, which helps to make the first shelf 201, the second shelf 202 and the second shelf 30 move synchronously. That is, as the first shelf 201 and the second shelf 202 move outward, the second shelf 30 rises. This synchronous design can further shorten the operation time, make it convenient to use and improve the user experience.

[0102] In some embodiments, the first transmission assembly 40 and the second transmission assembly 50 are symmetrically arranged. This not only helps the first shelf 201 and the second shelf 202 to move synchronously and over the same distance, but also helps to distribute the force evenly when driving the second shelf 30 to move.

[0103] Optionally, the first transmission assembly 40 includes: a first connecting rod 401, with its first end hinged to the housing 10 and its second end hinged to the first shelf 201; a second connecting rod 402, with its first end hinged to the housing 10 and its second end hinged to the first shelf 201, and the second connecting rod 402 is arranged parallel to the first connecting rod 401; a third connecting rod 403, with its first end hinged to the first end of the second connecting rod 402 and rotating synchronously; a fourth connecting rod 404, with its first end hinged to the second end of the third connecting rod 403 and its second end hinged to the second shelf 30; and a drive gear 405, located at the first end of the second connecting rod 402, for driving the second connecting rod 402 to rotate.

[0104] The first shelf 201, the first connecting rod 401, the second connecting rod 402, and the housing 10 form a parallelogram structure. When the drive gear 405 rotates counterclockwise, the second connecting rod 402 rotates counterclockwise simultaneously. At this time, the second end of the second connecting rod 402 pushes the first shelf 201 to move, and under the action of the first connecting rod 401, it ensures that the first shelf 201 moves outward relative to the top of the housing 10, thus ensuring the movement trajectory of the first shelf 201 and preventing it from deviating.

[0105] The first end of the third link 403 is hinged to the first end of the second link 402 and rotates synchronously with the second link 402. Therefore, when the second link 402 rotates counterclockwise, the third link 403 rotates counterclockwise with its first end as the origin. During the counterclockwise rotation, the fourth link 404 pushes the second shelf 30 upward. In this way, the first shelf 201 translates outward and the second shelf 30 moves upward, both driven by the drive gear 405 connected to the second link 402, ensuring synchronous movement of the first shelf 201 and the second shelf 30.

[0106] For ease of description, the initial state is defined as the state in which the second storage part 30 is located inside the box 10 and the first storage plate 201 covers the top of the second storage part 30, and the open state is defined as the state in which the second storage part 30 rises to the top of the box 10 and is arranged side by side with the first storage plate 201.

[0107] When the storage device changes from the initial state to the open state, the drive gear 405 rotates counterclockwise. When changing from the open state to the initial state, the drive gear 405 rotates clockwise. At this time, the first storage plate 201 moves inward under the drive of the second link 402 and the limiting action of the first link 401. The second storage part 30 moves downward under the action of the third link 403 and the fourth link 404 until it reaches the initial state.

[0108] In some embodiments, the first transmission assembly 40 further includes a drive member 406, which is connected to the drive gear 405 for driving the drive gear 405 to rotate; wherein the drive member 406 is a rotary handle or a motor.

[0109] When the drive component 406 is a rotary handle, rotating the rotary handle drives the drive gear 405 to rotate.

[0110] When the driving component 406 is a motor, the motor and the driving gear 405 are connected by a shaft. When the motor rotates, the driving gear 405 rotates synchronously.

[0111] Optionally, the second transmission assembly 50 includes: a fifth link 501, with its first end hinged to the housing 10 and its second end hinged to the second shelf 202; a sixth link 502, with its first end hinged to the housing 10 and its second end hinged to the second shelf 202, and the sixth link 502 is arranged parallel to the fifth link 501; a seventh link 503, with its first end hinged to the first end of the sixth link 502 and rotating synchronously; an eighth link 504, with its first end hinged to the second end of the seventh link 503 and its second end hinged to the second shelf 30; and a transmission gear 505, disposed at the first end of the sixth link 502, for driving the sixth link 502 to rotate; wherein the transmission gear 505 is meshed with a drive gear 405, and the rotation of the drive gear 405 drives the transmission gear 505 to rotate, thereby driving the sixth link 502 and the seventh link 503 to rotate.

[0112] The transmission gear 505 is meshed with the drive gear 405. When the drive gear 405 rotates counterclockwise, the transmission gear 505 rotates clockwise, and when the drive gear 405 rotates clockwise, the transmission gear 505 rotates counterclockwise.

[0113] The second shelf 202, the fifth link 501, the sixth link 502, and the housing 10 form a parallelogram structure. When the transmission gear 505 rotates clockwise, the sixth link 502 rotates clockwise simultaneously. At this time, the second end of the sixth link 502 pushes the second shelf 202 to move, and under the action of the fifth link 501, ensures that the second shelf 202 moves outward relative to the top of the housing 10, ensuring the movement trajectory of the second shelf 202 and preventing it from deviating.

[0114] The first end of the seventh link 503 is hinged to the first end of the sixth link 502 and rotates synchronously with the sixth link 502. Therefore, when the sixth link 502 rotates clockwise, the seventh link 503 rotates clockwise with its first end as the origin. During the clockwise rotation, the eighth link 504 pushes the second shelf 30 upward. In this way, the second shelf 202 is translated outward, and the second shelf 30 is moved upward, both driven by the transmission gear 505 connected to the sixth link 502, ensuring that the second shelf 202 and the second shelf 30 move synchronously.

[0115] In this document, the initial state is defined as the state in which the second storage part 30 is located inside the box 10 and the second storage plate 202 covers the top of the second storage part 30, and the open state is defined as the state in which the second storage part 30 rises to the top of the box 10 and is arranged side by side with the second storage plate 202.

[0116] When the storage device changes from the initial state to the open state, the drive gear 405 rotates counterclockwise, while the transmission gear 505 rotates clockwise. When changing from the open state to the initial state, the drive gear 405 rotates clockwise, and the transmission gear 505 rotates counterclockwise. At this time, the second storage plate 202, driven by the sixth link 502 and limited by the fifth link 501, moves inward. The second storage part 30, under the action of the seventh link 503 and the eighth link 504, moves downward until it reaches the initial state.

[0117] Optionally, the housing 10 is constructed with a first through groove 101 and a second through groove 102 penetrating the side wall; the second end of the fourth connecting rod 404 passes through the first through groove 101 and is hinged to the second storage part 30, and the second end of the fourth connecting rod 404 reciprocates along the first through groove 101; the second end of the eighth connecting rod 504 passes through the second through groove 102 and is hinged to the second storage part 30, and the second end of the eighth connecting rod 504 reciprocates along the second through groove 102; the fourth connecting rod 404 and the eighth connecting rod 504 together drive the second storage part 30 to move up and down.

[0118] The first through groove 101 provided on the side wall of the housing 10 defines the movement trajectory of the second end of the fourth connecting rod 404 and the movement trajectory of the second storage part 30. Similarly, the second through groove 102 provided on the side wall of the housing 10 defines the movement trajectory of the second end of the eighth connecting rod 504 and the movement trajectory of the second storage part 30.

[0119] Optionally, the first through slot 101 and the second through slot 102 are symmetrically arranged, and their heights and lengths are matched. This helps to ensure the stability and smoothness of the second storage section 30 during lifting and lowering movements.

[0120] In some embodiments, the first shelf 201 and / or the second shelf 202 are provided with drawer assemblies 60 for storage.

[0121] Drawer assemblies 60 are provided on the first shelf 201 and the second shelf 202, enabling them to not only serve as shelves but also as storage containers. Optionally, the drawer assemblies 60 are detachable. For example, several panels can be arranged around the edges of the first shelf 201 and the second shelf 202 to create a storage space. The panels can be magnetically attached together.

[0122] For example, when the first shelf 201 and the second shelf 202 are in their initial state, and both the first shelf 201 and the second shelf 202 are provided with drawer assemblies 60 at their tops, the drawer panels on the opposite or contacting edges of the first shelf 201 and the second shelf 202 are detachable, so that the storage space at the top of the first shelf 201 and the storage space at the top of the second shelf 202 are integrated into a single storage space, which is suitable for storing and placing special items.

[0123] In some embodiments, the second storage section 30 is a plate-like structure or a box-like structure; wherein, when the second storage section 30 is a box-like structure, the second storage section 30 has at least one independent storage space.

[0124] When the second storage unit 30, which has an independent storage space, rises to the top of the box 10, its edge not only serves as a support but also as a storage function, making it convenient for users to take things out and put them in.

The storage device includes a cabinet 10, a first storage section, a second storage section 30, and a third storage section 80. The cabinet 10 has a receiving space and is open at both the top and bottom; the first storage section includes two oppositely distributed and reversibly movable first storage plates 201 and second storage plates 202, which overlap the top of the cabinet 10; the first storage plates 201 and second storage plates 202 of the first storage section move relative to the cabinet 10 using the cabinet 10 as a carrier, undergoing various deformations to generate various load-bearing structures, which helps to meet diverse load-bearing needs, thereby improving the utilization rate of the refrigerator's internal space. The second storage section 30 is a box-type structure and is located inside the box body 10; the third storage section 80 is a box-type structure, at least partially located inside the box body 10, and is detachably connected to the box body 10; wherein, the third storage section 80 is fitted onto the second storage section 30 from bottom to top, and the third storage section 80 and the second storage section 30 enclose an adjustable-volume receiving cavity.

[0126] The refrigerator provided in this embodiment uses the first shelf 201 and the second shelf 202 of the first shelf section as a carrier to move relative to the cabinet 10 and undergo various deformations to generate various load-bearing structures, which helps to meet diverse load-bearing needs and thus improve the utilization rate of the refrigerator's internal space.
