Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a common household appliance that keeps food or other items at a constant low temperature. A refrigerator includes a cabinet and drawer assemblies housed within it. The drawer assembly includes a drawer liner, a vacuum pump, and the drawer body. The drawer body can be pulled out from within the drawer liner. When the drawer body is inside the drawer liner, the drawer body and the drawer liner create a storage space for preserving food. The vacuum pump evacuates air from this storage space, creating a negative pressure environment to improve the freshness of the food.

[0003] However, when the vacuum pump evacuates the storage space, the drawer liner deforms significantly, making it impossible to pull out the drawer body and thus preventing the food from being taken out. Utility Model Content

[0004] This application provides a refrigerator that solves the technical problem of drawer liner deformation causing the drawer body to be unable to be pulled out.

[0005] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0006] Box;

[0007] The door is located on the front side of the box.

[0008] Drawer assembly, located inside the cabinet, includes:

[0009] A drawer liner with a movable cavity, the opening of which faces the door. The drawer liner includes:

[0010] The main body of the container liner;

[0011] The first reinforcing structure is disposed on the outer wall surface of the main body of the container, and the first reinforcing structure is located away from the opening. The first reinforcing structure includes multiple first reinforcing ribs.

[0012] The second reinforcing structure is disposed on the outer wall surface of the main body of the box liner. The second reinforcing structure is connected to the first reinforcing structure and is disposed near the opening. The second reinforcing structure includes multiple second reinforcing ribs.

[0013] From the middle of the outer wall surface of the main body of the box liner to the side wall connected thereto, the arrangement of the first reinforcing ribs changes from dense to sparse, and the arrangement of the second reinforcing ribs changes from dense to sparse.

[0014] The drawer body has a movable cavity that can be pushed in or pulled out along the front and back direction of the box body. The drawer body and the inner box body can form a storage space.

[0015] The vacuum pump's suction port is connected to the drawer liner, and the vacuum pump extracts air from the containment space.

[0016] The first reinforcing structure enhances the strength and rigidity of the outer wall of the drawer body away from the opening, reducing deformation of the outer wall and preventing the drawer from being unable to be pulled out of the movable cavity. The second reinforcing structure increases the strength of the opening of the drawer body, helping to reduce deformation at the opening during use and preventing the drawer from being unable to be pulled out of the movable cavity. The first and second reinforcing ribs can be arranged from dense to sparse to ensure that the deformation of the drawer body is more uniform, avoiding excessive local deformation that could prevent the drawer from being pulled out, thereby improving the reliability of the drawer assembly.

[0017] In some embodiments of this application, the plurality of first reinforcing ribs include several annular reinforcing ribs, which are concentric and spaced apart.

[0018] This design allows the main body of the container to have a certain structural strength, while also reducing its weight and the cost of the container.

[0019] In some embodiments of this application, the spacing between adjacent annular reinforcing ribs is increased from the middle of the main body of the container to the side wall of the main body of the container.

[0020] During vacuum pumping, the central part of the chamber body may bear significant stress. A small spacing between adjacent annular reinforcing ribs and a denser arrangement of these ribs helps reduce deformation of the chamber body. In the area near the sidewalls of the chamber body, stress is relatively dispersed, and a larger spacing between adjacent annular reinforcing ribs and a sparser arrangement of these ribs reduces material usage and prevents excessive rigidity that could lead to fracture.

[0021] In some embodiments of this application, the plurality of first reinforcing ribs include several radial reinforcing ribs;

[0022] Several radial reinforcing ribs are arranged around the annular reinforcing ribs, radiating from the middle of the outer wall surface of the main body of the tank to the side wall connected thereto.

[0023] This design can distribute the stress in the middle area of ​​the outer wall surface of the liner to the side walls or corners, and the radial reinforcing ribs can enhance the stability under radial stress.

[0024] In some embodiments of this application, several radial reinforcing ribs and several annular reinforcing ribs are intersected and connected along the radial direction of the radial reinforcing ribs.

[0025] Circular reinforcing ribs provide circumferential support, while radial reinforcing ribs provide radial support. Cross-connection can form a mesh-like reinforcing rib structure, which can enhance the deformation resistance of the main body of the box liner.

[0026] In some embodiments of this application, a third reinforcing structure is provided on the outer wall surface of the main body of the box liner;

[0027] The third reinforcing structure ring is located around the first and second reinforcing structures, and extends to the side wall of the main body of the box liner.

[0028] This design allows the third reinforcing structure to transfer the stress from the first and second reinforcing structures from the outer wall to the side wall, preventing stress concentration. This ensures that the main body of the container maintains its shape and stability when subjected to various external forces.

[0029] In some embodiments of this application, a third reinforcing structure is provided on the outer wall surface of the main body of the box liner. The third reinforcing structure is arranged around the first reinforcing structure and the second reinforcing structure, and extends to the side wall of the main body of the box liner.

[0030] The second reinforcing rib includes several spaced transverse reinforcing ribs, with both ends of the transverse reinforcing ribs connected to the two sides of the third reinforcing structure;

[0031] The density of the transverse stiffeners is greater than that of the first and second stiffeners.

[0032] This design prevents deformation at the opening of the main body of the container from causing it to malfunction.

[0033] In some embodiments of this application, the second reinforcing rib includes a plurality of spaced longitudinal reinforcing ribs, which are intersected and connected to the transverse reinforcing ribs;

[0034] The first end of the longitudinal reinforcing rib is connected to the opening of the main body of the box, and the second end of the longitudinal reinforcing rib is connected to the first reinforcing structure.

[0035] This design allows the longitudinal reinforcing ribs to absorb and disperse these pressures, reducing localized deformation at the opening of the main body of the box.

[0036] In some embodiments of this application, the longitudinal stiffener includes a first longitudinal stiffener and a second longitudinal stiffener, and a second longitudinal stiffener is provided between adjacent first longitudinal stiffeners;

[0037] Several first longitudinal stiffeners and several second longitudinal stiffeners are respectively connected to several transverse stiffeners.

[0038] This design fills the support gaps and provides the support effect of longitudinal reinforcing ribs. This allows certain areas of the main body of the container to be supported, preventing deformation.

[0039] Secondly, embodiments of this application provide a refrigerator, comprising:

[0040] Box;

[0041] The door is located on the front side of the box.

[0042] Drawer assembly, located inside the cabinet, includes:

[0043] A drawer liner with a movable cavity, the opening of which faces the door. The drawer liner includes:

[0044] The main body of the container liner;

[0045] The first reinforcing structure is disposed on the outer wall surface of the main body of the container, and the first reinforcing structure is located away from the opening. The first reinforcing structure includes multiple first reinforcing ribs.

[0046] The second reinforcing structure is disposed on the outer wall surface of the main body of the box liner. The second reinforcing structure is connected to the first reinforcing structure and is disposed near the opening. The second reinforcing structure includes multiple second reinforcing ribs.

[0047] From the middle of the outer wall surface of the main body of the container to the side wall connected thereto, the first reinforcing ribs change from dense to sparse, and the second reinforcing ribs change from dense to sparse, which can improve the strength of the main body of the container.

[0048] The drawer body has a movable cavity that can be pushed in or pulled out along the front and back direction of the box body. The drawer body and the inner box body can form a storage space.

[0049] A vacuum pump, whose suction port is connected to the drawer liner, extracts air from the storage space.

[0050] The first reinforcing structure enhances the strength and rigidity of the outer wall of the drawer body away from the opening, reducing deformation of the outer wall and preventing the drawer from being unable to be pulled out of the movable cavity. The second reinforcing structure increases the strength of the opening of the drawer body, helping to reduce deformation at the opening during use and preventing the drawer from being unable to be pulled out of the movable cavity. The first and second reinforcing ribs can be arranged from dense to sparse to ensure that the deformation of the drawer body is more uniform, avoiding excessive local deformation that could prevent the drawer from being pulled out, thereby improving the reliability of the drawer assembly.

[0073] As described in the background art, refrigerators in related technologies include a cabinet and a drawer assembly disposed within the cabinet. The drawer assembly includes a drawer liner, a vacuum pump, and a drawer body. The drawer body can be pulled out from within the drawer liner. When the drawer body is inside the drawer liner, the drawer body and the drawer liner enclose a storage space for storing food. The vacuum pump can evacuate air from the storage space to create a negative pressure state, thereby improving the freshness of the food. However, when the vacuum pump evacuates air from the storage space, the drawer liner deforms significantly, making it impossible to pull out the drawer body and preventing the food from being retrieved.

[0074] In view of this, the refrigerator of this application embodiment includes a cabinet, a door, and a drawer assembly disposed within the cabinet. The drawer assembly includes a drawer liner, a drawer body, and a vacuum pump. The drawer body can push in or pull out the movable cavity of the drawer liner. The drawer body and the liner body can enclose a receiving space, and the vacuum pump can extract air from the receiving space to prolong the freshness of food stored in the receiving space. The drawer liner includes a liner body, a first reinforcing structure, and a second reinforcing structure. The first reinforcing structure is disposed on the outer wall surface of the liner body, and the second reinforcing structure is connected to the first reinforcing structure and disposed near the opening. The first reinforcing structure can enhance the strength and rigidity of the outer wall surface of the liner body away from the opening, reduce the deformation of the outer wall surface of the liner body, and prevent the drawer body from being unable to be pulled out from the movable cavity. The second reinforcing structure can increase the strength of the opening of the liner body, which helps to reduce the deformation of the opening of the liner body during use and prevents the drawer body from being unable to be pulled out from the movable cavity. The first and second reinforcing ribs can be arranged from dense to sparse to make the deformation of the drawer body more uniform, avoiding excessive local deformation that could prevent the drawer from being pulled out, thereby improving the reliability of the drawer assembly.

[0080] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0081] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0082] This application provides a refrigerator, which may include a cabinet. The cabinet provides support for the refrigerator and protects the internal components from physical damage. The cabinet may also provide space for storing food.

[0083] The refrigerator body may include an outer shell. The outer shell is the outermost layer of the refrigerator, which protects it from external impacts, scratches, and corrosion, and safeguards the internal refrigeration system and internal components from damage. The outer shell also provides thermal insulation.

[0084] Reference Figure 1 As shown, the refrigerator body may include an inner liner 10. The inner liner 10 is the storage space inside the refrigerator, used to store food. This can meet the user's food storage needs.

[0085] The enclosure may include a refrigerator compartment 110. The refrigerator compartment 110 can be set to a low but above-freezing temperature to slow down the rate of food spoilage and extend its shelf life.

[0086] The enclosure may include a freezer compartment. A freezer compartment can be set to a low temperature below freezing point, inhibiting the growth of microorganisms or reducing their activity, thus extending the shelf life of food.

[0087] A refrigerator includes a door. The door is located on the front of the refrigerator body. The door seals off the interior space of the refrigerator, preventing cold air from leaking out. Insulation material can be filled inside the door to reduce heat transfer, thereby reducing the refrigerator's energy consumption.

[0088] A refrigerator may include a condenser, which cools and condenses the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into a liquid state. After condensation in the condenser, the refrigerant temperature decreases, but the pressure remains relatively high.

[0089] The condenser is connected to the compressor, which ensures that the refrigerant circulates smoothly in the system and flows smoothly during compression, condensation, expansion and evaporation, thus ensuring refrigeration efficiency and effect.

[0090] Refrigerators may include a throttling valve, which can rapidly reduce the pressure of high-pressure liquid refrigerant. The throttling valve regulates the cooling capacity of the refrigeration system by controlling the flow rate of the refrigerant.

[0091] A refrigerator may include an evaporator, which absorbs heat to change the refrigerant from a liquid state to a gaseous state, thereby lowering the temperature inside the refrigerator.

[0092] For example, the refrigeration process of a refrigerator is as follows: The compressor compresses the low-pressure, low-temperature refrigerant gas, transforming it into a high-temperature, high-pressure gas. The compressed refrigerant then enters the condenser, which is connected to the compressor. The condenser then condenses the compressed refrigerant into a liquid state, releasing heat to the surrounding environment. Next, the expansion valve expands the high-pressure liquid refrigerant in the condenser into a low-pressure liquid refrigerant. Finally, the low-pressure liquid refrigerant absorbs heat in the evaporator, completely evaporating into a gaseous state, lowering the internal temperature of the refrigerator, and returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator utilizes the heat exchange of the refrigerant to achieve the refrigeration effect.

[0093] Continue to refer to Figure 1 As shown, the refrigerator may include a drawer assembly 20, which is disposed inside the refrigerator body. The drawer assembly 20 can extend the shelf life of food.

[0094] Reference Figure 2 As shown, the drawer assembly 20 may include a drawer liner 200, which can divide the internal space of the cabinet for storing different foods. The drawer liner 200 is disposed inside the cabinet.

[0095] The drawer liner 200 is surrounded by a movable cavity 250. The movable cavity 250 is provided with an opening 251, which faces the door.

[0096] Reference Figure 3 As shown, the drawer assembly 20 may include a drawer body 300. The drawer body 300 is provided with a receiving cavity for storing food.

[0097] Along the front-to-back direction of the cabinet, the drawer body 300 is pushed into the movable cavity 250 through the opening 251 to keep the drawer body 300 sealed, thus extending the food's shelf life. The drawer body 300 can be pulled out of the movable cavity 250 along the direction of movement, making it easy to retrieve food from inside the drawer body 300.

[0098] The drawer body 300 can extend the shelf life of food by reducing oxygen levels. By removing air from the storage space to reduce oxygen levels inside the drawer body 300, most bacteria and molds grow and multiply slowly in a low-oxygen environment, thus delaying food spoilage.

[0099] Drawer assembly 20 may include a vacuum pump (not shown). The vacuum pump can generate negative pressure by driving an impeller to rotate at high speed using its own motor. The suction port of the vacuum pump is connected to the drawer liner 200, and the negative pressure is used to extract air from the storage space to delay the spoilage of food in the storage space.

[0100] Drawer assembly 20 may include a pressure relief device (not shown). A vacuum pump extracts air from the receiving space to create a negative pressure area. The pressure relief device breaks the negative pressure in the receiving space, making it easier to open the drawer body 300 and retrieve food from it.

[0101] Reference Figure 4 , Figure 5 and Figure 6 As shown, the drawer liner 200 may include a liner body 210, which can determine the basic structure and shape of the drawer liner 200.

[0102] The drawer body 300 is located within the movable cavity 250. The drawer body 300 and the inner box body 210 enclose a closed storage space, which can store food to delay its spoilage. The drawer body 300 facilitates the user's classification and storage of food, making food management and retrieval easier.

[0103] The drawer liner 200 may include a first reinforcing structure 220. The first reinforcing structure 220 is disposed on the outer wall surface of the liner body 210, and is located away from the opening 251. The first reinforcing structure 220 can enhance the strength and rigidity of the outer wall surface of the liner body 210 away from the opening 251, and reduce the deformation of the outer wall surface of the liner body 210.

[0104] The first reinforcing structure 220 includes multiple first reinforcing ribs. From the center of the outer wall surface of the container body 210 to the side wall of the container body 210, the first reinforcing ribs can vary in density from dense to sparse. That is, the density of the first reinforcing ribs gradually decreases from the center of the outer wall surface towards the side wall.

[0105] In the central region of the chamber body 210, the dense first reinforcing ribs can improve the strength and rigidity of the chamber body 210, and enhance its bending and compressive resistance. When the vacuum pump is drawing a vacuum, the dense first reinforcing ribs can reduce the deformation of the chamber body 210.

[0106] The corner where the side wall of the drawer body 210 connects to the outer wall has high geometric rigidity due to its structure. When the vacuum pump draws a vacuum, the deformation at the corner is small. Near the corner, the first reinforcing ribs are sparsely arranged to make the deformation of the drawer body 210 more uniform, avoiding excessive local deformation that could prevent the drawer body 300 from being pulled out, thereby improving the reliability of the drawer assembly 20.

[0107] This design avoids increasing the rigidity of the main body 210 of the box by adding too many first reinforcing ribs, which can reduce the amount of material used, reduce the weight of the main body 210 of the box, and save the manufacturing cost of the box.

[0108] The drawer liner 200 may include a second reinforcing structure 230. The second reinforcing structure 230 is connected to the first reinforcing structure 220 and is located near the opening 251. The second reinforcing structure 230 can increase the strength at the opening 251 of the liner body 210, which helps to reduce the deformation at the opening 251 of the liner body 210 during use and prevents the drawer body 300 from being unable to be pulled out from the movable cavity 250.

[0109] The second reinforcing structure 230 includes multiple second reinforcing ribs. The second reinforcing ribs gradually decrease in density from the middle of the outer wall surface of the container body 210 to the side wall of the container body 210. In other words, the density of the second reinforcing ribs gradually decreases from the middle of the outer wall surface to the side wall of the container body 210.

[0110] In the central region of the opening 251 of the main body 210 of the container, the dense second reinforcing ribs can improve the strength and rigidity of the opening 251, and enhance the bending and compressive resistance of the opening 251. When the vacuum pump is drawing a vacuum, the dense second reinforcing ribs can reduce the deformation of the opening 251 of the main body 210 of the container.

[0111] The corner where the side wall of the drawer body 210 connects to the outer wall has high geometric rigidity due to its structure. When the vacuum pump draws a vacuum, the deformation at the corner is small. Therefore, near the corner, the second reinforcing ribs are sparsely arranged to make the deformation at the opening 251 of the drawer body 210 more uniform, avoiding excessive local deformation that could prevent the drawer body 300 from being pulled out, thereby improving the reliability of the drawer assembly 20.

[0112] Reference Figure 7 As shown, the multiple first reinforcing ribs may include several annular reinforcing ribs 221. The annular reinforcing ribs 221 can improve the strength and rigidity of the box body 210. Furthermore, the design and manufacturing process of the annular reinforcing ribs 221 is relatively simple, which can reduce the manufacturing cost of the box body.

[0113] For example, the annular reinforcing rib 221 can be a closed annular reinforcing rib 221, which can be set in the middle region of the box body 210 to reduce the deformation of the box body 210.

[0114] For example, the annular reinforcing rib 221 can be an open-ring type, which can be set in the area near the side wall of the container body 210, and can adapt to the spatial arrangement of the container body 210.

[0115] Several annular reinforcing ribs 221 are arranged concentrically. That is to say, the annular reinforcing ribs 221 are all arranged around the smallest circle, which can reduce the design and manufacturing difficulty of the annular reinforcing ribs 221.

[0116] While ensuring that the main body 210 of the container has a certain structural strength, several annular reinforcing ribs 221 are arranged at intervals, which can reduce the weight of the main body 210 of the container and reduce the cost of the container.

[0117] From the middle of the outer wall surface of the tank body 210 to the side wall of the tank body 210, the spacing between adjacent annular reinforcing ribs 221 increases. During the vacuum pump's evacuation process, the middle of the tank body 210 may bear significant stress. The smaller spacing and denser arrangement of the adjacent annular reinforcing ribs 221 helps reduce the deformation of the tank body 210. In the area near the side wall of the tank body 210, the stress is relatively dispersed. The larger spacing and sparser arrangement of the adjacent annular reinforcing ribs 221 reduces material usage and prevents excessive rigidity from causing fracture under stress.

[0118] For example, the spacing between adjacent annular reinforcing ribs 221 can gradually increase with equal arithmetic values, which can reduce the design difficulty.

[0119] For example, the spacing between adjacent annular reinforcing ribs 221 near the middle region of the main body 210 of the container can be set to be smaller, while the spacing between adjacent annular reinforcing ribs 221 near the side wall region of the main body 210 of the container can be set to be larger.

[0120] Multiple first reinforcing ribs may include several radial reinforcing ribs 222. The radial reinforcing ribs 222 radiate from the center of the outer wall surface of the tank body 210 towards the side wall of the tank body 210, dispersing the stress in the center of the outer wall surface of the tank body 210 to the side wall or corners. The radial reinforcing ribs 222 enhance the stability under radial stress. During vacuum pumping, the stress borne by the center of the tank body 210 can be dispersed to a larger area through the radial reinforcing ribs 222, thereby reducing the local deformation in the center of the tank body 210.

[0121] Along the radial direction of the radial reinforcing ribs 222, the radial reinforcing ribs 222 and the annular reinforcing ribs 221 are intersected and connected. The annular reinforcing ribs 221 provide circumferential support, while the radial reinforcing ribs 222 provide radial support. The intersecting connection can form a mesh-like reinforcing rib structure, which can enhance the deformation resistance of the box body 210.

[0122] Several radial reinforcing ribs 222 can be connected to different annular reinforcing ribs 221. The annular dimension of the inner annular reinforcing rib 221 is smaller, and the radial reinforcing ribs 222 can be arranged according to the annular dimension of the annular reinforcing rib 221, which can save materials.

[0123] For example, the annular reinforcing rib 221 includes a first annular reinforcing rib, a second annular reinforcing rib, and a third annular reinforcing rib arranged concentrically and at intervals. The plurality of radial reinforcing ribs 222 include a plurality of first radial reinforcing ribs, a plurality of second radial reinforcing ribs, and a plurality of third radial reinforcing ribs. The plurality of first radial reinforcing ribs, a plurality of second radial reinforcing ribs, and a plurality of third radial reinforcing ribs are respectively connected to the first annular reinforcing rib, the second annular reinforcing rib, and the third annular reinforcing rib. This arrangement satisfies the space requirements of the radial reinforcing ribs 222 and improves the rigidity and strength of the main body 210 of the enclosure.

[0124] Reference Figure 8 and Figure 9 As shown, a third reinforcing structure 240 is provided on the outer wall surface of the container body 210. The second end of the third reinforcing structure 240 extends to the side wall of the container body 210. The side wall and corners have high rigidity and small deformation. By extending the third reinforcing structure 240 to the side wall of the container body 210, the rigidity and strength of the third reinforcing structure 240 can be enhanced.

[0125] The first end of the third reinforcing structure 240 is arranged around the periphery of the first reinforcing structure 220 and the second reinforcing structure 230. The third reinforcing structure 240 can transfer the stress of the first reinforcing structure 220 and the second reinforcing structure 230 from the outer wall to the side wall, thus avoiding stress concentration. This arrangement allows the main body 210 of the box liner to maintain its shape and stability when subjected to various external forces.

[0126] Reference Figure 10 As shown, the second reinforcing rib includes several spaced longitudinal reinforcing ribs 232, which are arranged along the extending direction of the container body 210. The longitudinal reinforcing ribs 232 can enhance the longitudinal rigidity and strength of the container body 210.

[0127] The first end of the longitudinal reinforcing rib 232 is connected to the opening 251 of the main body 210 of the container, and the second end of the longitudinal reinforcing rib 232 is connected to the first reinforcing structure 220. The connection between the longitudinal reinforcing rib 232 and the opening 251 of the main body 210 of the container and the first reinforcing structure 220 helps to disperse the force and resist deformation. When the main body 210 of the container is subjected to the pressure generated by the negative pressure when the vacuum pump is pumping air, the longitudinal reinforcing rib 232 can absorb and disperse these pressures, reducing local deformation at the opening 251 of the main body 210 of the container.

[0128] For example, the liner body 210 has an edge at the opening 251, and the first end of the longitudinal reinforcing rib 232 is connected to the edge. The second end of the longitudinal reinforcing rib 232 is connected to the radial reinforcing rib 222. When the liner body 210 is subjected to external force, the longitudinal reinforcing rib 232 can guide the stress to be transmitted along its extension direction and dispersed to other areas of the liner body 210, thereby avoiding local stress concentration.

[0129] The longitudinal reinforcing rib 232 includes a first longitudinal reinforcing rib 2321 and a second longitudinal reinforcing rib 2322. Adding a second longitudinal reinforcing rib 2322 between adjacent first longitudinal reinforcing ribs 2321 can fill the support gap and provide the supporting effect of the longitudinal reinforcing rib 232. This allows a portion of the main body 210 of the box liner to be supported, preventing its deformation.

[0130] Several first longitudinal stiffeners 2321 and several second longitudinal stiffeners 2322 are connected to several transverse stiffeners 231. That is, adjacent first longitudinal stiffeners 2321 are provided with second longitudinal stiffeners 2322. Several first longitudinal stiffeners 2321 are connected to some transverse stiffeners 231, and several second longitudinal stiffeners 2322 are connected to other transverse stiffeners 231. By setting different longitudinal stiffeners 232, multi-layered longitudinal support is provided, enhancing the longitudinal stiffness and strength of the box liner body 210.

[0131] The second reinforcing rib includes several spaced transverse reinforcing ribs 231. The transverse reinforcing ribs 231 can increase the transverse stiffness of the opening 251 of the box body 210 and reduce transverse deformation.

[0132] The two ends of the transverse reinforcing rib 231 can be connected to both sides of the third reinforcing structure 240. When the main body of the container liner 210 is subjected to external force, the transverse reinforcing rib 231 can guide the stress to be transmitted along its extension direction and dispersed by the third reinforcing structure 240 to the side wall and other areas of the main body of the container liner 210, thereby avoiding local stress concentration and enhancing the stability of the main body of the container liner 210.

[0133] The density of the transverse reinforcing rib 231 is greater than that of the first and second reinforcing ribs. This higher density increases the rigidity at the opening 251 of the main body 210. The opening 251 of the main body 210 must withstand the vacuuming force of the vacuum pump and the contact force from contact with other parts during opening and closing. This design prevents deformation at the opening 251 of the main body 210, which could render the main body 210 unusable.

[0134] The transverse stiffeners 231 and longitudinal stiffeners 232 are cross-connected to form a grid structure. The cross-connection makes the stress more evenly distributed in the grid structure formed by the stiffeners, reducing structural damage caused by stress concentration.
