[0044] Refrigerators are a common appliance in daily life and are now widely used. Users can use refrigerators to store food to prevent it from spoiling.

[0045] Refrigerators typically have shelves within their storage space, each comprising shelves for placing items. In related art, the shelves are typically of fixed size. However, items placed in refrigerators vary in size and height, making fixed-size shelves incapable of accommodating items of varying sizes, hindering user usability.

[0046] Based on this, some embodiments of the present application provide a refrigerator. The refrigerator includes a cabinet, which defines a storage cavity. The refrigerator also includes an inner liner, which is arranged in the storage cavity. A storage chamber is provided in the inner liner. The refrigerator also includes a shelf, which is arranged in the storage chamber. The shelf includes two brackets and a shelf. The two brackets are respectively connected to two opposite inner walls of the storage chamber, and each bracket is provided with a support rail, which extends from the rear side of the cabinet to the front side of the cabinet. The shelf is slidably connected to the support rails of the two brackets. When the shelf moves along the support rail from the front side of the cabinet to the rear side of the cabinet under the action of an external force, the end of the shelf close to the rear side of the cabinet exits the support rail and is rolled up; when the shelf moves along the support rail from the rear side of the cabinet to the front side of the cabinet under the action of an external force, the rolled-up part of the shelf is driven to enter the support rail.

[0047] In this way, the size of the shelf can be infinitely adjusted by pushing and pulling the shelf, which makes it convenient for users to flexibly adjust the size of the support surface of the shelf according to their own needs.

[0048] The technical solution of the present application is described in detail below with reference to the embodiments.

[0049] 1 , in some embodiments of the present application, a refrigerator includes a housing 100 .

[0050] The cabinet 100 forms the overall appearance of the refrigerator and is generally rectangular in shape. The top and bottom of the cabinet 100 are opposite ends, and the direction from the top to the bottom is the height of the cabinet 100. The left side and the right side of the cabinet 100 are opposite ends, and the direction from the left to the right is the width of the cabinet 100. The front and the back of the cabinet 100 are opposite ends, and the direction from the front to the back is the thickness of the cabinet.

[0051] In actual use, the front side of the cabinet 100 is usually facing the user, and the back side of the cabinet 100 is usually facing the wall. In the embodiment of the present application, the direction from the front side of the cabinet 100 to the back side of the cabinet 100 is called the first direction (i.e., direction S1 in Figure 1), and the direction from the back side of the cabinet 100 to the front side of the cabinet 100 is called the second direction (i.e., direction S2 in Figure 1).

[0052] The box body 100 defines an accommodating cavity therein, and the accommodating cavity includes an opening.

[0053] Please refer to FIG. 2 , the refrigerator further includes an inner container 1 , which is disposed in the accommodating cavity of the box body 100 .

[0054] The interior of the inner tank 1 defines a storage chamber 11, which is configured to store food and other items. The storage chamber 11 has an opening, which is arranged toward the front side of the box body, so that a user can take items into and out of the storage chamber 11 through the opening. The storage chamber 11 can be a refrigerator, a freezer, etc. The temperature inside the storage chamber 11 can be a refrigerated temperature environment (e.g., 0°C to 4°C), a frozen temperature environment (e.g., -18°C to -22°C), or a normal temperature environment (e.g., 5°C to 15°C).

[0055] The refrigerator further includes a door (not shown), which is disposed at the opening of the accommodating cavity and is rotatably connected to the box body 100 to open or close the storage chamber 11 .

[0056] It is understandable that the refrigerator further includes a refrigeration system. The refrigeration system is installed in the housing 100 and is configured to provide cold air to the refrigeration chamber 11.

[0057] The refrigeration system includes components such as the compressor, evaporator, condenser, filter drier, return air pipe, and throttling device. These components are distributed in different locations within the cabinet according to their structural characteristics to meet the requirements of their corresponding functions.

[0058] In some embodiments, the working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process.

[0059] The compression process begins when the refrigerator is connected to an external power source and the thermostat contacts are closed. Low-temperature, low-pressure refrigerant from the evaporator is drawn into the compressor, compressed into high-temperature, high-pressure refrigerant gas, and then discharged into the condenser.

[0060] The condensation process includes: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled into a saturated refrigerant vapor at room temperature and high pressure, and then cooled into a saturated refrigerant liquid.

[0061] The throttling process includes: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device, where it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure.

[0062] The evaporation process involves the following: wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat and vaporize. During this vaporization process, the refrigerant lowers the temperature of the evaporator and its surroundings, achieving cooling and turning the refrigerant into a low-temperature, low-pressure gas.

[0063] The refrigerant from the evaporator returns to the compressor and the above process is repeated. In this way, the refrigerator converts energy through the change of the refrigerant state, transferring the heat inside the refrigerator to the air outside the refrigerator, thus completing the refrigerator's refrigeration cycle.

[0064] In some embodiments, the refrigerator further includes an air supply system installed in the cabinet and configured to provide power for the flow of cold air.

[0065] The air supply system includes a fan and a guide cavity. In some embodiments, the air inlet end of the guide cavity is arranged close to the fan, and the air outlet end of the guide cavity is arranged away from the fan.

[0066] In other embodiments, the air outlet end of the guide cavity is arranged close to the fan, and the air inlet end of the guide cavity is arranged away from the fan.

[0067] The fan drives the air in the guide cavity, and the evaporator is correspondingly arranged in the guide cavity. The cold air cooled by the evaporator flows along the guide cavity under the drive of the fan, and finally enters the refrigeration chamber 11 to perform cooling operation on the refrigeration chamber 11.

[0068] The refrigerator also includes at least one shelf 2. The at least one shelf 2 is disposed within the storage chamber 11. The at least one shelf 2 is configured to store items and is further configured to divide the storage chamber 11 into multiple storage areas, allowing different categories of items to be placed in different storage areas. This not only facilitates user access to items and prevents different items from interfering with each other, but also improves the utilization of the refrigerator's internal space.

[0069] In some embodiments, the refrigerator includes a plurality of shelves 2, which are arranged along the height of the refrigerator, with spaces between adjacent shelves 2. It is understood that the present application does not limit the number and arrangement of the shelves.

[0070] 3 and 4 , in some embodiments, the shelf 2 includes a layer board 20 .

[0071] The shelf 20 includes a first portion 21 and a second portion 22. The first portion 21 is configured to extend from the rear side of the box 100 to the front side of the box 100 to form a support surface for placing items. The second portion 22 is connected to the first portion 21 and is disposed near the rear side of the box 100.

[0072] It can be understood that the support surface is arranged in a horizontal direction to prevent items placed on the support surface from sliding off.

[0073] The shelf 2 includes a bracket 23 . The bracket 23 is connected to the inner wall of the storage chamber 11 , and the shelf 20 is connected to the bracket 23 , so that the shelf 20 is installed in the storage chamber 11 through the bracket 23 .

[0074] In some embodiments, two brackets 23 are provided, and the two brackets 23 are arranged opposite to each other along the thickness direction of the box body 100, and the two brackets 23 are respectively connected to the inner walls of the refrigerator compartment 11 on both sides arranged along the thickness direction of the box body 100.

[0075] 5 and 6 , the shelf 2 further includes a support rail 231. Specifically, each bracket 23 is provided with the support rail 231 on one side facing the other bracket 23. The support rail 231 extends from the front end to the rear end of the bracket 23.

[0076] In some embodiments, the shelf 2 further includes a storage rail 232. Specifically, each bracket 23 includes a storage rail 232 that extends from the rear end toward the front end of the bracket 23, with one end of the storage rail 232 communicating with one end of the support rail 231. For example, the storage rail 232 is located below the support rail 231, or above the support rail 231.

[0077] It can be understood that in the above embodiment, the form of the support rail 231 and the storage rail 233 is not limited, as long as the shelf 20 can slide along the support rail 231 and the storage rail 233. For example, the support rail 231 and the storage rail 233 are grooves opened in the bracket 23.

[0078] The first portion 21 and the second portion 22 of the layer plate 20 are slidably connected between the support rails 231 of the two brackets 23, and at least a portion of the second portion 22 is slidably connected to the storage rail 232. When the first portion 21 moves along the support rail 231 in the first direction S1 under the push of an external force, it pushes at least a portion of the second portion 22 into the storage rail 232, so that the area of ​​the support surface formed by the layer plate 20 is reduced. When the first portion 21 moves along the support rail 231 in the second direction S2 under the pull of an external force, it pulls at least a portion of the second portion 22 from the storage rail 232 into the support rail 231, so that the first portion and the second portion jointly form a support surface, thereby increasing the area of ​​the support surface. In the above embodiment, the support rail 231 and the storage rail 232 are provided on the two brackets 23 arranged opposite to each other. The user pushes and pulls the first portion 21 of the shelf 20, causing the first portion 21 to move along the support rail 231, thereby driving the second portion 22 to move between the support rail 231 and the storage rail 232. When the second portion 22 moves to the support rail 231, it can support items. When the second portion 22 moves to the storage rail 232, the second portion 22 is retracted. In this way, the user can adjust the length of the second portion 22 entering the support rail 231 according to usage needs, achieving infinite adjustment of the storage size of the shelf 2, which is more practical.

[0079] It will be appreciated that in some embodiments, the range of motion of the first portion 21 and the second portion 22 is from the time the second portion 22 fully enters the storage rail 232 to the time the second portion 22 fully exits the storage rail 232 and enters the support rail. When the second portion 22 fully enters the storage rail 232, the first portion 21 forms a support surface for the shelf 20. When at least a portion of the second portion 22 enters the support rail 231, the first portion 21 and the second portion 22 that has entered the support rail 231 jointly form a support surface.

[0080] In some embodiments, the storage rail 232 extends from the rear end of the bracket 23 toward the front end of the bracket 23 , and the rear end of the storage rail 232 is connected to the rear end of the support rail 231 .

[0081] Since the support rail 231 extends from the front end to the rear end of the bracket 23, the storage rail 232 extends from the rear end of the bracket 23 toward the front end of the bracket 23, and the rear end of the storage rail 232 is connected to the rear end of the support rail 231, so that the space of the bracket 23 can be reasonably utilized while ensuring the smooth folding of the second part 22 of the shelf 20, and the height size of the bracket 23 will not be increased due to the setting of the storage rail 232.

[0082] In some embodiments, the rear end of each support rail 231 of the bracket 23 is connected to the rear end of the corresponding storage rail 232 through a transition rail 233 .

[0083] When the second part 22 moves between the support rail 231 and the storage rail 232, the transition rail 233 provided between the support rail 231 and the storage rail 232 guides the second part 22, making the movement of the second part 22 smoother without jamming, and also allowing the user to adjust the shelf 2 more smoothly.

[0084] In some embodiments, the support rail 231 extends horizontally from the front to the rear of the bracket 23, and the storage rail 232 gradually approaches the support rail 231 from the rear to the front. The vertical dimension of the bracket 23 gradually decreases from the rear to the front of the bracket 23. The front end of the bracket and the front end of the storage rail both refer to the end facing the front of the box, while the rear end of the bracket and the rear end of the storage rail both refer to the end facing the rear of the box.

[0085] The support rail 231 extends horizontally from the front to the rear of the bracket 23. When the first portion 21 and the second portion 22 are connected to the support rail 231, the first portion 21 and the second portion 22 are on the same horizontal plane, providing stable support for items. Furthermore, the storage rail 232 gradually approaches the support rail 231 from the rear end to the front end, gradually decreasing the vertical dimension of the bracket 23 from the rear end to the front end. This reduces the size of the front end of the bracket 23, making it less likely for the bracket 23 to obstruct the user when placing or removing items.

[0086] It can be understood that in other embodiments, the support rail 231 and the storage rail 232 can also be arranged in parallel.

[0087] In some embodiments, the shelf 2 further includes a support rod 24 , and the support rod 24 is connected between the two brackets 23 .

[0088] The support rods 24 are beneficial to enhancing the overall stability of the shelf 2, so that the shelf 2 has a strong supporting strength, ensuring that the storage needs of the user are met.

[0089] In some embodiments, the support rod 24 is located at the front end of the storage rail 232 , and the side of the support rod 24 facing the storage rail 232 includes an arc-shaped guiding surface 241 .

[0090] By arranging the support rod 24 at the front end of the storage rail 232, it is helpful to block the second part 22 from entering the storage rail 232. In addition, the support rod 24 has an arc-shaped guide surface 241 on the side facing the storage rail 232, so that when the second part 22 moves to the front end of the storage rail 232 and abuts the support rod 24, the second part 22 can move upward along the guide surface 241 and be supported by the support rod 24, thereby preventing the second part 22 from directly hitting the support rod 24 when the second part 22 moves along the storage rail 212 to the position of the support rod 24, and the support rod 24 can also support the second part 22.

[0091] In some embodiments, a fixing rod 25 is further connected between the rear ends of the two brackets 23 to further enhance the overall stability of the shelf 2 .

[0092] Figures 7 to 9 illustrate schematic diagrams of the first portion 21 of the shelf 20. In some embodiments, the first portion 21 is a flat plate. For example, the first portion 21 may be a plastic plate, a glass plate, or a metal plate. Opposite sides of the first portion 21 are respectively disposed in support rails 231, allowing the first portion 21 to move along the support rails 231.

[0093] In some embodiments, guide bars 211 are provided on both sides of the first portion 21 connecting to the bracket 23, and each guide bar 211 extends along the front-to-back direction of the first portion 21. The guide bars 211 on both sides of the first portion 21 are disposed in a one-to-one correspondence within the support rails 231 of the two brackets 23.

[0094] By arranging guide bars 211 on both sides of the first part 21 and the guide bars 211 being arranged in the support rail 231 , the first part 21 of the layer plate 20 is connected between the two brackets 23 and can move along the support rail 231 .

[0095] In some embodiments, the guide bar 211 is provided with a slider 212. For example, the slider 212 is disposed at the bottom of one end of the guide bar 211. The slider 212 abuts against the support rail 231 to reduce frictional resistance when the guide bar 211 moves along the support rail 231, allowing the first portion 21 to move more smoothly along the support rail 231, thereby facilitating user adjustment of the shelf 2.

[0096] In some embodiments, an operating portion 213 is provided at the top and / or bottom of the front end of the first portion 21. The operating portion 213 is configured to allow a user to push or pull the first portion of the layer board 20.

[0097] In some embodiments, the bottom of the front end of the first portion 21 extends downward to form the handle 213 for the user to grasp, thereby driving the layer plate 20 to move along the support track 231 for user convenience.

[0098] In other embodiments, the front end top of the first portion 21 extends upward to form a handle.

[0099] In some embodiments, a groove 214 is provided at the bottom of the first portion 21, adjacent to the handle 213, for the user's fingers to enter. Once the user's fingers are inserted into the groove 214, the contact area with the handle 213 is increased, allowing for a more secure grip and easier movement of the first panel 21. Furthermore, the provision of the groove 214 reduces the vertical dimension of the handle 213 while ensuring a secure grip. This prevents interference between items and the handle 213 when the user is placing or removing items, thus minimizing usability.

[0100] In other embodiments, the bottom or top of the first portion 21 is provided with a groove 214 without including the handle 213 .

[0101] Figures 9 and 10 illustrate the structure of the second portion of the layer plate in some embodiments of the present application. In some embodiments, the second portion 22 includes a plurality of chain plates 220. The chain plates 220 are arranged along the thickness of the box 100, with every two adjacent chain plates 200 being rotatably connected, and the chain plates adjacent to the first portion 21 are rotatably connected to the first portion 21.

[0102] Each link plate 220 includes a plate body 221. The length of the plate body 221 in the width direction of the box body 100 is greater than the length in the thickness direction of the box body 100.

[0103] Each chain plate 220 also includes two connecting blocks 222, extending from either end of the plate 221 along one side of the thickness of the box 100. A clearance notch 223 is defined at each end of the plate 221 along the other side of the thickness of the box 100. When two adjacent chain plates 220 are connected, the two connecting blocks 222 of one plate 221 correspond to each other and fit within the two clearance notches 223 of the other plate 221, forming a rotational connection with the other plate 221.

[0104] In this way, the rotational connection of adjacent chain plates 220 is achieved, and when the adjacent chain plates 220 are flush, the gap therebetween is small, which can prevent small items from falling through the gap between the adjacent chain plates 220 .

[0105] It should be noted that when the user pushes or pulls the first portion 21, the multiple chain plates 220 move back and forth between the support rail 231 and the storage rail 232, and the chain plates 220 pass through the curved transition rail 233. To ensure that the multiple chain plates 220 pass through the transition rail 233 smoothly and without jamming, the curvature and length of the transition rail 233 are adapted to the width of each chain plate 220, so that each chain plate 22 can pass through the transition rail 233. In this way, the infinite adjustment of the size of the shelf 2 is smoother and more stable.

[0106] In some other embodiments, the storage track 232 may also be spiral-shaped. When the user pushes the first portion 21 in the first direction S1, the first portion 21 pushes the multiple chain plates 220 of the second portion 22 from the support track 231 into the storage track 232. Then, the multiple chain plates 220 gradually rotate from the outer ring of the spiral storage track 232 into the inner ring of the spiral storage track 232. Similarly, the multiple chain plates 220 of the second portion 22 can be retracted through the storage track 232. When the user pulls the first portion 21 in the second direction S2, the first portion 21 pulls the multiple chain plates 220 of the second portion 22 gradually out of the storage track 232 and into the support track 231, allowing the multiple chain plates 220 to play a supporting role in the shelf 2.

[0107] In some embodiments, the first portion 21 and the second portion 22 of the shelf 20 may also have the same structure. For example, the first portion 21 and the second portion 22 may both be formed by a plurality of rotatably connected chain plates, or the first portion 21 and the second portion 22 may both be made of a rollable material. In this way, the second portion 22 and at least a portion of the first portion 21 of the shelf 20 may both enter the storage rail 232, thereby increasing the adjustable range of the support surface size of the shelf 20.

[0108] In some other embodiments, the storage rail 232 and the transition rail 233 may be omitted.

[0109] That is, when the user pushes the first portion 21 in the first direction S1 to move along the support rail 231, the first portion 21 pushes the multiple chain plates 22 of the second portion 22 to move along the support rail 231 in the first direction S1 and exit the support rail 231, so that at least a portion of the multiple chain plates 22 are suspended behind the shelf 2. When the user pulls the first portion 21 in the second direction S2 to move along the support rail 231, the first portion 21 pulls at least a portion of the multiple chain plates 22 back onto the support rail 231 in sequence, thereby enabling the user to infinitely adjust the size of the support surface of the shelf 2, meeting the various storage needs of customers and providing high practicality.

[0110] It should be noted that the second layer 22 is a plate-like structure with a certain thickness to provide sufficient support strength to meet the storage needs of users. In some embodiments, the chain plate 220 can be a plastic plate, a glass plate, or a metal plate.

[0111] In summary, compared with the refrigerators in the related art in which the shelf size cannot be adjusted or is only adjusted in a single way, the refrigerator provided by the above embodiments has a shelf 2 in which the user can push and pull the first part 21 of the shelf 20 to move along the support rail 231 according to storage needs, so as to push and pull the multiple chain plates 220 of the second part 22 to move. When the second layer 22 moves to the support rail 231, the second layer 22 can support the items. After the second layer 22 exits the support rail 231, the multiple second layer 22 can be folded up, thereby realizing stepless adjustment of the size of the shelf 2, meeting the user's various storage needs, and being more practical.

[0112] Furthermore, in the refrigerator shelf 2 of the above embodiment, the connections between the first portion 21, the bracket 23, and the multiple chain plates 220 of the second portion 22 do not require glue or fasteners such as screws. Therefore, assembly of the first portion 21, the bracket 23, and the multiple chain plates 220 is simpler and more convenient, and the assembly reliability is high. Furthermore, due to the simple assembly of the first portion 21, the bracket 23, and the multiple chain plates 220, disassembly and assembly are also more convenient during repairs, facilitating maintenance. In particular, with multiple chain plates 220, if a single chain plate 220 is damaged, only the damaged chain plate 220 needs to be replaced, resulting in low maintenance costs.

[0113] In other embodiments of the present application, another layered structure is provided.

[0114] As shown in FIG. 12 , FIG. 14 , FIG. 23 and FIG. 25 , the shelf 2 includes a layer plate 20 , which defines a support surface for placing items, and the support surface extends from the rear side of the box body 100 to the front side of the box body 100 .

[0115] The shelf 2 includes a bracket 23 , which is connected to the inner wall of the storage chamber 11 . The shelf 20 and the bracket 23 are connected to each other so that the shelf 20 is placed in the storage chamber through the bracket 23 .

[0116] In some embodiments, two brackets 23 are designed, and the two brackets 23 are detachably connected to the shelf 20 to increase the reliability of the shelf 20 being arranged in the storage chamber 11.

[0117] The two brackets 23 are correspondingly arranged along the width direction of the box body 100 , and the two brackets 23 are correspondingly connected to the inner walls of the storage chamber 11 on both sides arranged along the width direction of the box body 100 .

[0118] In this embodiment, the layer plate 20 is designed to be retractable, which not only facilitates the adjustment of the size of the support surface, but also facilitates the retraction of the layer plate 20. Compared with the previous embodiment, since the layer plate 20 can be retracted, the adjustable range of the size of the support surface is increased.

[0119] Specifically, as shown in FIG. 28 , the layer plate 20 includes a first portion 21 , and the first portion 21 is used to define a support surface.

[0120] The layer plate 20 includes a second portion 22 connected to the first portion 21 . The second portion 22 can be rolled up to reduce occupied space.

[0121] The first portion 21 can be rolled up into the second portion 22 , and the second portion 22 can be stretched into the first portion 21 .

[0122] The first portion 21 of the layer plate 20 is defined to form a support surface, and the size of the unfolded portion of the layer plate 20 is adjusted to adjust the size of the layer plate along the thickness direction of the box body 100 .

[0123] By rolling up the unrolled portion of the layer board 20 , it is convenient to arrange the layer board 20 in the storage room.

[0124] It is understood that in this embodiment, the first portion 21 can be fully rolled up to form the second portion 22. For example, when the layer board 20 is no longer needed, the entire layer board 20 can be rolled up, and the layer board 20 does not form a support surface. It is also understood that the second portion 22 can also be fully extended to form the first portion 21 to increase the area of ​​the support surface. This increases the adjustable range of the support surface size of the layer board 20.

[0125] As shown in Figures 19 and 22-24, the shelf 20 includes a support rail 231, which extends from the rear side of the box body 100 to the front side of the box body 100; the shelf 20 can slide along the support rail 231 to adjust the size of the support surface from the rear side of the box body 100 to the front side of the box body 100.

[0126] By making the layer plate 20 slide along the support rail 231 and using the support rail 231 to guide the sliding of the layer plate 20, not only the reliability of the rolling and stretching movement of the layer plate 20 can be increased, but also the firmness of the arrangement of the layer plate 20 can be increased.

[0127] The first portion 21 is disposed in the support rail 231 , and the support rail 231 provides support for the first portion 21 to increase the strength of the support surface.

[0128] It should be noted that the first portion 21 can slide along the support rail 231 in the first direction S1 and be rolled up into the second portion 22 ; the second portion 22 can slide along the support rail 231 in the second direction S2 and be extended into the first portion 21 .

[0129] In some embodiments of the present application, as shown in Figure 22, the support rail 231 is provided on the bracket 23. Providing the support rail 231 on the bracket 23 can reduce the number of components of the shelf 2, improve production efficiency and facilitate assembly.

[0130] In some embodiments, each bracket 23 includes a first support plate 2301 , and the first support plate 2301 contacts the bottom of the layer plate 20 to support the layer plate 20 .

[0131] In some embodiments, the first support plate 2301 is provided with a support portion 23011 , and the support portion 23011 is used to increase the contact area between the first support plate 2301 and the layer plate 20 , thereby increasing the supporting effect of the first support plate 2301 on the layer plate 20 .

[0132] The support portion 23011 is disposed close to one end of the first support plate 2301 facing the rear side of the box body 100 ; the support portion 23011 is in contact with the bottom of the layer plate 20 .

[0133] In some embodiments, the first support plate 2301 extends from the rear side of the box body 100 toward the front side of the box body 100 , and the layer plate 20 slides along the extension direction of the first support plate 2301 .

[0134] Each bracket 23 includes a third support plate 2302 . The third support plate 2302 and the first support plate 2301 are interconnected and intersected with each other to increase the overall strength of the bracket 223 .

[0135] The third support plate 2302 is disposed along the height direction of the box body 100 , and the third support plate 2302 is disposed corresponding to the inner wall of the storage chamber 11 along the width direction of the box body 100 .

[0136] Each bracket 23 includes a second support plate 2303 , and the second support plate 2303 extends along the rear side of the box body 100 toward the front side of the box body 100 .

[0137] The second support plate 2303 is substantially parallel to the first support plate 2301 , for example, located above the first support plate 2301 , and the second support plate 2303 and the first support plate 2301 are at a certain distance from each other along the height direction of the box 100 , so that the second support plate 2303 and the first support plate 2301 jointly define a support track 231 .

[0138] It should be noted that the second support plate 2303 is connected to the upper end of the third support plate 2302 .

[0139] The side of the second support plate 2303 away from the third support plate 2302 and the side of the first support plate 2301 away from the third support plate 2302 jointly define an opening. The openings of the two brackets 220 are arranged correspondingly so that the ends of the shelf 20 along the width direction of the box body 100 are correspondingly arranged within the two support rails 231, thereby increasing the reliability of the movement of the shelf 20.

[0140] In other embodiments of the present application, as shown in Figures 6 and 11, the shelf 2 includes a connector 26, which is connected to the bracket 23, and the extension direction of the connector 26 is parallel to the extension direction of the bracket 23. For example, the connector 23 is located above the bracket 23. The connector 26 and the bracket 23 together define a support track 231.

[0141] Specifically, the bracket 220 includes a first support plate 2301 . The first support plate 2301 contacts the bottom of the layer plate 20 to support the layer plate 20 .

[0142] In some embodiments, the first support plate 2301 is provided with a support portion 23011 , and the support portion 23011 is used to increase the contact area between the first support plate 2301 and the layer plate 20 , thereby increasing the supporting effect of the first support plate 2301 on the layer plate 20 .

[0143] The support portion 23011 is disposed close to one end of the first support plate 2301 facing the rear side of the box body 100 ; the support portion 23011 is in contact with the bottom of the layer plate 20 .

[0144] In some embodiments, the first support plate 2301 extends from the rear side of the box body 100 toward the front side of the box body 100 , and the layer plate 20 slides along the extension direction of the first support plate 2301 .

[0145] The bracket 23 includes a third support plate 2302 . The third support plate 2302 and the first support plate 2301 are connected to each other and intersect with each other to increase the overall strength of the bracket 23 .

[0146] The third support plate 2302 is disposed along the height direction of the box body 100 , and the third support plate 2302 is disposed corresponding to the inner wall of the storage chamber along the width direction of the box body 100 .

[0147] As shown in FIG21 , the connector 26 includes a first connecting plate 261 extending from the rear side of the housing 100 toward the front side of the housing 100. The first connecting plate 261 is disposed correspondingly to and parallel to the first support plate 2301. For example, the first connecting plate 261 is located above the first support plate 2301, and the first connecting plate 261 and the first support plate 2301 together define the support track 231.

[0148] When the layer plate 20 slides along the support rail 231 , the first connecting plate 261 is located above the layer plate 20 , and the first supporting plate 2301 contacts the bottom of the layer plate 20 .

[0149] The connecting member 26 includes a second connecting plate 262 . The second connecting plate 262 and the first connecting plate 261 are connected to each other and intersect with each other to increase the overall strength of the connecting member 230 .

[0150] The second connecting plate 262 and the third supporting plate 2302 are connected to each other, so that the connecting member 26 and the bracket 23 are connected to each other.

[0151] The second connecting plate 262 is disposed along the height direction of the box body 100 so that the second connecting plate 262 and the third supporting plate 2302 are disposed correspondingly, thereby facilitating the connection between the second connecting plate 262 and the third supporting plate 2302 .

[0152] It should be noted that the second connecting plate 262 is located on a side of the third supporting plate 2302 away from the other bracket 23 .

[0153] In some embodiments, the second connecting plate 262 and the third support plate 2302 can be riveted, welded, or connected to each other by fasteners such as bolts or screws to increase the reliability and firmness of the connection between the connector 26 and the bracket 23.

[0154] As shown in Figure 20, the bracket 23 is provided with a limiting portion 2304, which is located at the top of the bracket 23 and is arranged close to the end of the bracket 23 facing the rear side of the box body 100. The end of the connecting member 26 facing the rear side of the box body 100 is in contact with the limiting portion 2304 to locate the connection position of the connecting member 26 and the bracket 23.

[0155] When the connecting member 26 is connected to the bracket 23 , one end of the connecting member 26 facing the rear side of the box body 100 abuts against the limiting portion 2304 to locate the connection position of the connecting member 26 and the bracket 23 .

[0156] In some embodiments, the limiting portion 2304 is arranged to protrude from the first support plate 2301 to form a step above the bracket 220 , so that the connecting member 26 abuts against the step to position the connecting member 26 .

[0157] As shown in Figures 15, 16, 18, and 24-27, the shelf 2 includes a damping plate 27, which is arranged in the support rail 231 and in contact with the layer plate 20. The damping plate 27 is used to increase the damping coefficient of the layer plate 20 when it slides along the support rail 231, so that the layer plate 20 can remain stationary at a certain position on the support rail 231, preventing the layer plate 20 from automatically rolling up, and increasing the reliability of the layer plate 20 extending.

[0158] The damping plate 27 extends from the rear side of the box body 100 to the front side of the box body 100. The damping plate 27 is located above the floor plate 20.

[0159] In some embodiments, the damping plate 27 is connected to the upper surface of the inner wall of the support rail 231 .

[0160] In some embodiments, the damping plate 27 is a TPU (Thermoplastic Polyurethane) gasket.

[0161] The shelf 2 includes a rotating shaft 28 , and the second portion 22 is rolled up around the rotating shaft 28 .

[0162] In some embodiments, the rotating shaft 28 is disposed near the rear side of the box body 100 , so that the second portion 22 is disposed near the rear side of the box body 100 after being rolled up.

[0163] It should be noted that the rotating shaft 28 and the layer plate 20 are in contact with each other, and the second portion 22 is a solid structure after being rolled up.

[0164] As shown in FIG. 16 and FIG. 23 , the rotating shaft 28 is connected to one end of the bracket 23 close to the rear side of the box body 100 , so that the rotating shaft 28 is mounted on the bracket 23 and the bracket 23 provides support for the rotation of the rotating shaft 28 .

[0165] It should be noted that both ends of the rotating shaft 28 are connected to the two brackets 23 respectively, so as to enhance the supporting effect of the brackets 23 on the rotating shaft 28 .

[0166] The uppermost end of the rolled-up second portion 22 is usually flush with the plane where the first portion 21 is located, so as to increase the reliability and stability of the layer plate 20 sliding along the support rail 231 .

[0167] When the total length of the entire layer board 20 is constant, different sizes of the supporting surface will result in different sizes of the second portion 22. Accordingly, the size of the second portion 22 along the height direction of the box body 100 after being rolled up will also be different.

[0168] It can be seen that in order to ensure that the uppermost end of the second portion 22 after being rolled up is flush with the plane where the first portion 21 is located, the height of the rotating shaft 28 needs to be adaptively changed as the layer plate 20 is rolled up and stretched.

[0169] In view of this, as shown in FIG. 19 and FIG. 22 , the bracket 23 is provided with a connecting portion 2305 , and the connecting portion 2305 extends from the top of the box body 100 to the bottom of the box body 100 .

[0170] The end of the rotating shaft 28 is disposed in the connecting portion 2305 and can slide up and down along the connecting portion 2305 .

[0171] When the layer plate 20 slides along the support rail 231 , the rotating shaft 28 slides along the connecting portion 2305 , so that the height of the rotating shaft 28 changes dynamically with the movement of the layer plate 20 .

[0172] When the layer plate 20 is rolled up, the size of the second part 22 increases, resulting in an increase in the size of the second part 22 along the height direction of the box body 100 after being rolled up. At this time, the rotating shaft 28 slides downward along the connecting portion 2305, increasing the distance between the rotating shaft 28 and the first support plate 2301.

[0173] When the layer 20 is stretched, the size of the second part 22 is reduced, resulting in a smaller size of the second part 22 along the height direction of the box 100 after being rolled up. At this time, the rotating shaft 28 slides upward along the connecting portion 2305, reducing the distance between the rotating shaft 28 and the first support plate 2301.

[0174] In some embodiments, as shown in FIG. 28 , the layer plate 20 is a metal coil, which can be easily rolled up and has a certain strength when unfolded, so as to support items.

[0175] It should be noted that metal coils are common knowledge in this field and will not be described in detail here.

[0176] In other embodiments, the layer plate 20 adopts a honeycomb flexible structure with zero Poisson's ratio, which can be stretched and contracted in the pulling direction without changing the width.

[0177] Considering that the hardness and bending strength of metal coils are relatively weak, when the weight of the items is large, the metal coils are easily bent when placed on the items. Therefore, in other embodiments, the layer plate 20 is designed as a chain structure to increase the hardness and strength of the layer plate 20 when it is unfolded.

[0178] As shown in Figures 29-31 , the deck 20 includes a plurality of chain plates 220. The length of the chain plates 220 is arranged along the width of the box 100. At least some of the chain plates 220 are arranged from the rear side of the box 100 to the front side of the box 100. Adjacent chain plates 220 are rotatably connected to each other. The chain plates 220 can slide along the support rails 231. In other words, in this embodiment, both the first portion 21 and the second portion 22 of the deck 20 are composed of chain plates.

[0179] In some embodiments, the chain plate 213 may be a glass plate, a metal plate, etc., which not only allows the layer plate 20 to be rolled up, but also allows the layer plate 20 to have greater strength and hardness after being unfolded.

[0180] The connection method between adjacent chain plates is as described above and will not be repeated here.

[0181] In some embodiments, the shelf 2 may include a storage box (not shown), which is disposed at one end of the bracket 23 close to the rear side of the box body 100 , and the second portion 22 is disposed in the storage box after being rolled up.

[0182] In other embodiments, the surface of the layer board 20 can be customized with different patterns and can be made of different materials.

[0183] In the above-mentioned refrigerator, the working principle of the shelf 2 is: when it is necessary to increase the size of the support surface along the thickness direction of the box body 100, the layer plate 20 is pulled forward along the thickness direction of the box body 100, so that the layer plate 20 slides toward the front side of the box body 100 along the support rail 231, and the size of the first part 21 of the layer plate 20 is increased, thereby increasing the size of the support surface defined by the first part 21 of the layer plate 20.

[0184] When it is necessary to reduce the size of the support surface along the thickness direction of the box body 100, roll up the layer plate 20 so that the layer plate 20 slides toward the rear side of the box body 100 along the support track 231 to reduce the size of the first part 21 of the layer plate 20, thereby reducing the size of the support surface defined by the first part 21 of the layer plate 20.

[0185] It should be noted that, in some embodiments, the shelf 2 includes an elastic structure, and when the layer plate 20 needs to be rolled up, the layer plate 20 is automatically rolled up under the action of the elastic structure.

[0186] The automatic rolling up of the elastic structure layer 20 is a conventional technical means in this field and will not be described in detail here.

[0187] It should also be noted that, in some embodiments, the bracket 23 may be provided with a hook, and the bracket 23 is hung on the inner wall of the storage chamber through the hook.

[0188] The refrigerator utilizes retractable shelves 20 to adjust the support surface's dimensions along the thickness of the cabinet 100, allowing for complete flexibility in the stacking of shelves 2. Using metal coils or chain structures to replace the glass panels of traditional shelves 2 simplifies the overall structure of shelves 2 and provides stability when in place. Furthermore, shelves 2 are easy to clean and maintain, facilitating subsequent repairs and replacements. Damaged shelves 20 require only replacement.

[0189] Finally, it should be noted that the various technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0190] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
