Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0038] Please see Figures 1 to 7 This application provides a food storage container assembly 100, including an upper cover plate 20 and a food storage container 60. The food storage container 60 has a storage space inside and a first opening 64 communicating with the storage space.

[0039] The upper cover plate 20 has an inner cavity and a second opening 22 communicating with the inner cavity. At least one set of modified atmosphere film assemblies 30 is provided in the inner cavity. The modified atmosphere film assembly 30 includes a modified atmosphere film 31, which can extend out from the second opening 22 and cover the first opening 64 of the food storage box 60.

[0040] It should be noted that by setting the modified atmosphere membrane 31 to cover the first opening 64 of the food storage container 60, the modified atmosphere membrane 31 can be used to adjust the gas composition (such as oxygen, carbon dioxide, etc.) in the storage space of the food storage container 60 to control the respiration of food (such as meat, fruits and vegetables, etc.), thereby slowing down its physiological metabolic process and extending the storage period of the food.

[0041] The food storage container assembly 100 provided in this application embodiment has an upper cover plate 20 above the food storage container 60, and a modified atmosphere film assembly 30 is provided in the inner cavity of the upper cover plate 20. The modified atmosphere film 31 can extend from the second opening 22 of the upper cover plate 20 and cover the first opening 64 of the food storage container 60. At this time, the gas inside the storage space needs to exchange gas with the external environment through the modified atmosphere film 31. That is, the gas regulation function of the modified atmosphere film 31 can be used to improve the food preservation function of the storage space, so that the color and taste of the food placed in the storage space remain relatively stable and the shelf life is extended, thereby improving the user experience. When the modified atmosphere film 31 is not needed, it can be retracted. At this time, the first opening 64 of the food storage container 60 is connected to the outside, and the gas inside the storage space can directly exchange gas with the external environment, thereby changing the preservation performance of the storage space.

[0042] Please see Figure 2 and Figure 3 For example, multiple sets of modified atmosphere membrane assemblies 30 can be disposed in the inner cavity of the upper cover plate 20, and the multiple sets of modified atmosphere membrane assemblies 30 are arranged sequentially and spaced apart. Here, multiple sets refer to two or more sets, such as three sets, four sets, five sets, six sets, seven sets, eight sets, etc.

[0043] It should be noted that different ingredients have different requirements for modified atmosphere film 31. Different ingredients have different respiratory characteristics (including respiratory rate and respiratory quotient), and the gas composition in the preservation space will also be different in the same time. The oxygen concentration and carbon dioxide concentration will also be different. Therefore, the same film should be used for the same type of ingredients to obtain the best modified atmosphere preservation effect.

[0044] Understandably, by setting up multiple modified atmosphere film assemblies 30, it is convenient to replace the modified atmosphere film assemblies 30. For example, the multiple modified atmosphere film assemblies 30 can be set to include modified atmosphere film for fruits, vegetables, mushrooms, meat, seafood, or dried goods. When the type of food stored in the food storage container 60 changes, the corresponding modified atmosphere film type can be replaced.

[0045] It is understandable that when the food stored in the storage space is fruit, vegetables, mushrooms, meat, seafood or dried goods, modified atmosphere film can be used for fruit, vegetables, mushrooms, meat, seafood or dried goods respectively.

[0046] For example, the material of the modified atmosphere membrane 31 can be polyethylene (PE), polycaprolactone (PL), polylactic acid (PLA), polybutylene adipate / terephthalate (PBAT), etc. In other embodiments, the modified atmosphere membrane 31 can also be a multilayer composite membrane.

[0047] Please see Figure 6 The modified atmosphere film assembly 30 further includes a winding assembly, on which the modified atmosphere film 31 is wound. The modified atmosphere film 31 has a fixed end and a free end 311 disposed opposite to each other. The fixed end is connected to the winding assembly, and the modified atmosphere film 31 can be extended or retracted by the movement of its free end 311.

[0048] Understandably, by setting up a winding assembly, the modified atmosphere film 31 can be retracted and wound onto the winding assembly when it is not needed, and when it is needed, it can be pulled out to cover the first opening 64 of the storage space.

[0049] Please see Figure 6 The winding assembly includes at least one spring 32, and the fixed end of the modified atmosphere film 31 is connected to the spring 32.

[0050] For example, the number of the mainsprings 32 can be multiple, and the multiple mainsprings 32 are arranged in parallel. All of the multiple mainsprings 32 are connected to the modified atmosphere diaphragm 31. Here, multiple means two or more, such as three, four, five, six, seven, eight, etc.

[0051] Understandably, by setting up a spring 32 and connecting the fixed end of the modified atmosphere membrane 31 to the spring 32, elastic potential energy can be accumulated inside the spring 32 when the modified atmosphere membrane 31 is pulled out. When the modified atmosphere membrane 31 needs to be retracted, a contraction force is generated because the spring 32 stores elastic potential energy. This contraction force acts on the modified atmosphere membrane 31, causing it to retract and wind onto the winding assembly. The contraction force of the spring 32 continues to act until the modified atmosphere membrane 31 is completely wound back onto the winding assembly. At this point, the spring 32 returns to its initial state, and the elastic potential energy is released.

[0052] Please see Figure 5 The modified atmosphere film assembly 30 also includes a housing 33, in which at least a portion of the winding assembly and the modified atmosphere film 31 are disposed. The housing 33 has a third opening 331, and the free end 311 of the modified atmosphere film 31 extends out from the third opening 331.

[0053] For example, the outer shell 33 is a cylinder with a hollow structure, and the third opening 331 is provided on the side of the cylinder.

[0054] It is understood that by providing the housing 33, at least a portion of the winding assembly and the modified atmosphere film 31 are disposed within the housing 33, which can protect the winding assembly and the modified atmosphere film 31. By providing the second opening 22 on the housing 33, the modified atmosphere film 31 can extend or retract through the second opening 22.

[0055] Please see Figure 3 The food storage container assembly 100 also includes a first fixing member 41 and a second fixing member 42, which are detachably connected to the upper cover plate 20.

[0056] The outer casing 33 has a first recess 332 and a second recess at its two ends respectively. When the first fixing member 41 is connected to the upper cover plate 20, a part of the first fixing member 41 enters the first recess 332; when the second fixing member 42 is connected to the upper cover plate 20, a part of the second fixing member 42 enters the second recess.

[0057] For example, the first recessed portion can be a groove or a through hole, and the second recessed portion can be a groove or a through hole.

[0058] It is understandable that by setting the first fixing member 41 and the second fixing member 42, not only can the modified atmosphere membrane assembly 30 be supported, but also, when it is necessary to replace the modified atmosphere membrane assembly 30, the first fixing member 41 and the second fixing member 42 can be removed to replace the modified atmosphere membrane assembly 30.

[0059] In some embodiments, the first fixing member 41 and the second fixing member 42 can both be screws. The upper cover plate 20 is provided with a first threaded hole and a second threaded hole. The first fixing screw is threadedly connected to the first threaded hole, and the second fixing screw is threadedly connected to the second threaded hole.

[0060] In some embodiments, the first fixing member 41 and the second fixing member 42 may both be pins, and the first fixing member 41 and the second fixing member 42 may be connected to the upper cover plate 20 by magnetic attraction.

[0061] For example, scenarios in which the modified atmosphere membrane assembly 30 needs to be replaced include: 1. The gas regulation function of the modified atmosphere membrane 31 is weakened or lost; 2. The modified atmosphere membrane 31 is damaged; 3. The type of food in the storage space changes, thus requiring the use of a specific type of modified atmosphere membrane 31.

[0062] Please see Figure 1 and Figure 2 The modified atmosphere film assembly 30 further includes a first connector 11, which is connected to the free end 311 of the modified atmosphere film 31. When the modified atmosphere film 31 covers the first opening 64 of the food storage box 60, the first connector 11 is fixedly connected to the food storage box 60.

[0063] Please see Figure 7 The food storage container 60 includes a bottom plate 61 and a first side plate 62 connected together. The bottom plate 61 and the first side plate 62 together enclose the storage space. The first side plate 62 encloses the first opening 64 at one end away from the bottom plate. The outer surface of the first side plate 62 is provided with a second connector 12, which is used to fix and connect with the first connector 11.

[0064] It is understandable that by setting the first connector 11 and the second connector 12 to be fixedly connected, the free end 311 of the modified atmosphere film 31 can be fixed to the first side plate 62 of the food storage box 60.

[0065] Please see Figure 7 For example, the second connector 12 is provided with a locking part 121, which is engaged with the first connector 11.

[0066] For example, the engaging portion 121 may be a snap-fit ​​groove or a snap-fit ​​hole.

[0067] For example, at least one of the first connector 11 and the second connector 12 contains a magnetic material, and the first connector 11 and the second connector 12 are connected by magnetic attraction.

[0068] Please see Figure 8 The food storage container assembly 100 also includes a fixing cover plate 70, which has a fourth opening 714. The fixing cover plate 70 is disposed between the upper cover plate 20 and the food storage container 60. The fixing cover plate 70 and the food storage container 60 cooperate with each other to fix the modified atmosphere film 31 when the modified atmosphere film 31 covers the first opening 64 of the food storage container 60.

[0069] Understandably, by setting the fixed cover plate 70, the modified atmosphere film 31 can be fixed when it covers the first opening 64 of the food storage box 60, thus preventing the modified atmosphere film 31 from loosening and falling off, which would affect the food storage performance of the food storage box 60. By setting the fourth opening 714 on the fixed cover plate 70, the modified atmosphere film 31 can be exposed, so that the modified atmosphere film 31 can play a role in gas regulation between the external environment and the storage space.

[0070] For example, the fixing plate 70 and the food storage container 60 can be connected by a slide rail, magnetic attraction or snap fastener.

[0071] For example, the shape of the fourth opening 714 can be rectangular (rectangular or square) or circular.

[0072] Please see Figure 8 For example, the fixed cover plate 70 includes a connected plate body 71 and a side portion 72. The side portion 72 is disposed on the side of the plate body 71 away from the upper cover plate 20. The plate body 71 is provided with the fourth opening 714. It can be understood that by providing the side portion 72, the edge of the modified atmosphere film 31 can be clamped between the side portion 72 and the first side plate 62 of the food storage box 60, thereby further reinforcing the modified atmosphere film 31.

[0073] Please see Figure 3 and Figure 4 For example, the upper cover 20 includes a cover body 24 and a second side plate 25 connected together. The second side plate 25 is disposed towards the food storage box 60. The second side plate 25 and the cover body 24 together enclose the inner cavity. The end of the second side plate 25 away from the cover body encloses the second opening 22. The second side plate 25 is provided with a notch 23. The notch 23 communicates with the inner cavity of the upper cover 20 so that outside air can enter the inner cavity of the upper cover 20 through the notch 23 and enter the storage space of the food storage box 60 after exchanging gas with the modified atmosphere membrane 31.

[0074] This application also provides a refrigeration device, including the food storage container assembly from any of the above embodiments.

[0075] For example, the refrigeration equipment can be a refrigerator, freezer, beverage cooler, wine cooler, freezer box, ice cream machine, ice maker, etc.

[0076] The food storage container assembly and refrigeration equipment provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
