Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a moisturizing component and a refrigerator. Background Art

[0002] Current refrigerators have a single space and a single function, and most of them can only achieve space cooling.

[0003] Direct-cooling freezers, when placed inside a sealed box and fresh ingredients like beef, often result in the beef retaining a significant amount of moisture at room temperature. When exposed to very low temperatures, the water vapor pressure inside the beef exceeds that in the surrounding air, causing it to release a significant amount of moisture. This moisture, when exposed to temperatures below 0°C, will freeze and frost, directly affecting the beef's taste and preventing it from maintaining its freshness.

[0004] During normal operation, air-cooled freezers constantly circulate air within them. Placing fresh beef in an air-cooled freezer will produce the same effect as placing it in a direct-cooled freezer: moisture will precipitate from the beef's surface, forming frost and ice. However, if holes are opened in the air-cooled freezer to allow air to flow in and remove surface moisture, this will accelerate the release of moisture from the beef's surface. While the beef will not freeze and the frost will not form, the beef will become tougher more quickly, affecting its taste.

[0005] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0006] There is no module in the existing freezer that can achieve both quick freezing and moisturizing.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0064] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0068] Unless otherwise stated, the term "plurality" means two or more.

[0069] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0070] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0071] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0072] Combine Figures 1 to 20 As shown, an embodiment of the present disclosure provides a refrigerator, comprising: a cabinet body 50 and a storage basket. The storage basket, placed within the cabinet body 50, helps users separate different types of food, facilitating management and retrieval while preventing cross-contamination. The use of the storage basket allows for more efficient utilization of the refrigerator's vertical space, increasing storage capacity. The storage basket is typically easy to remove and clean, helping to maintain a clean interior. Furthermore, the storage basket prevents food from directly contacting the bottom of the refrigerator, thereby preventing moisture from condensation.

[0073] The cabinet 50 has an air outlet 501 formed on its inner wall. A storage basket is located within the cabinet 50 and has a first air duct structure and a second air duct structure with different airflow directions. The airflow direction of the first air duct structure matches the airflow direction of the air outlet 501. The design of the first and second air duct structures facilitates the flow of cold air from the air outlet 501 of the cabinet 50 into the storage basket, ensuring that the food in the basket is kept chilled.

[0074] The different airflow directions of the first and second air duct structures facilitate the dispersed circulation of cold air flowing into the storage basket, thereby ensuring uniform freezing of the food, avoiding localized overcooling, and improving the overall freezing effect. Given the different airflow directions of the first and second air duct structures, the airflow direction of the second air duct structure at least intersects with the airflow direction of the first air duct structure. The airflow direction of the first air duct structure matches the direction of the airflow from air outlet 501, meaning that the airflow from air outlet 501 flows directly into the first air duct structure.

[0075] In the refrigerator provided by the embodiment of the present disclosure, the airflow blown out from the air outlet 501 flows into the first air duct structure. The airflow directions of the first air duct structure and the second air duct structure are different, which helps to disperse the cold air flowing into the storage basket, thereby ensuring uniform freezing of food, avoiding local overcooling, and improving the overall freezing effect.

[0076] Optionally, the storage basket includes a moisturizing box 10 for storing items, and the first air duct structure includes: a first ventilation part 101, which is constructed on the side wall of the moisturizing box 10 and is arranged in a surrounding manner; wherein, a partial area of ​​the first ventilation part 101 is arranged corresponding to the air outlet 501 of the cabinet body 50.

[0077] The first ventilation part 101 is arranged around the moisturizing box 10. The air flow blown out from the air outlet 501 flows into the moisturizing box 10 through the first ventilation part 101 and then flows out. It can not only freeze the food in the moisturizing box 10, but also quickly blow away the water vapor in the moisturizing box 10 to avoid frost and ice.

[0078] Part of the first ventilation part 101 is arranged corresponding to the air outlet 501 of the cabinet 50, which helps the air flow from the air outlet 501 to flow into the moisturizing box 10 and facilitates the air flow in the moisturizing box 10 to flow out through other areas of the first ventilation part 101.

[0079] Optionally, the first ventilation portion 101 is located at the upper portion of the moisturizing box 10. This can prevent the first ventilation portion 101 from being located too low and being blocked by the food in the moisturizing box 10, thereby affecting the inflow and outflow of air.

[0080] Optionally, the first ventilation portion 101 includes a plurality of first ventilation holes 1011 , and the plurality of first ventilation holes 1011 are evenly spaced, which is conducive to uniform air supply and uniform stress on the entire moisturizing box 10 .

[0081] Optionally, the first ventilation hole 1011 may be a hole-shaped structure or a polygonal structure, but is not limited to the above two structures. As long as it is a conventional structure that can achieve ventilation, it can be considered as the first ventilation hole 1011.

[0082] Optionally, the second air duct structure includes: a third ventilation part 102, which is constructed on the side wall of the moisturizing box 10 and is arranged for opposite side ventilation; wherein, the third ventilation part 102 is arranged to avoid the side wall where the air outlet 501 of the cabinet 50 is located.

[0083] The third ventilation part 102 is set for opposite side ventilation and avoids the side wall of the cabinet 50 where the air outlet 501 is located. In this way, the air flow from the air outlet 501 of the cabinet 50 flows directly into the moisturizing box 10 from the first ventilation part 101, and the circulating air flow in the cabinet 50 flows into the moisturizing box 10 through the third ventilation part 102. The two air flows have different directions and are set vertically.

[0084] The third ventilation portion 102 includes a plurality of third ventilation holes 1021 , which are evenly spaced apart, thereby facilitating uniform air supply and uniform stress on the entire moisturizing box 10 .

[0085] Optionally, the third ventilation hole 1021 may be a hole-shaped structure or a polygonal structure, but is not limited to the above two structures. As long as it is a conventional structure that can achieve ventilation, it can be considered as the third ventilation hole 1021.

[0086] For example, the humidor 10 is a rectangular parallelepiped structure, with four side walls, namely, a first side wall, a second side wall, a third side wall, and a fourth side wall. The first and third side walls are width-related, while the second and fourth side walls are length-related. The first side wall corresponds to the air outlet 501 of the cabinet 50. The third ventilation portion 102 is located on the second and fourth side walls.

[0087] The following table shows the humidity conditions in the moisturizing box 10 when the third ventilation portion 102 is located on the length side wall and the width side wall.

[0088]

[0089] The experimental data above indicates that when the third ventilation portion 102 is located on the longitudinal sidewall, the humidity within the humidifier 10 is higher than when the third ventilation portion 102 is located on the width sidewall. Therefore, when the third ventilation portion 102 is located on the longitudinal sidewall, away from the air outlet 501 of the cabinet 50, i.e., not directly connected to the air outlet 501, a better moisturizing effect can be achieved.

[0090] Optionally, the storage basket further includes: a moisture-permeable cover plate 20, which is provided on the moisturizing box 10 and is located between the first ventilation part 101 and the third ventilation part 102; wherein the first ventilation part 101 is located above the third ventilation part 102 and is parallel to the third ventilation part 102.

[0091] The moisturizing box 10 having the moisture-permeable cover plate 20 can control the humidity of the stored food through the moisture-permeable cover plate 20 and has a moisturizing function.

[0092] The moisture-permeable cover 20 is located between the first ventilation portion 101 and the third ventilation portion 102, and the first ventilation portion 101 is located above the third ventilation portion 102. Through the first ventilation portion 101 corresponding to the air outlet 501, the air flow from the air outlet 501 quickly flows into the moisturizing box 10 through the first ventilation portion 101 and flows through the top of the moisture-permeable cover 20, which can blow the water vapor transmitted from the moisture-permeable cover 20 away from the moisture-permeable cover 20, thereby preventing the water vapor from frosting above the moisture-permeable cover 20.

[0093] When the moisture-permeable cover 20 covers the top opening of the humidor 10, ventilation within the humidor 10 is maintained through the third vent 102. Furthermore, the third vent 102 is positioned away from the air outlet 501, preventing the third vent 102 from rapidly blowing away moisture within the humidor 10 and affecting the moisturizing effect within the humidor 10. Furthermore, the third vent 102 located below the moisture-permeable cover 20 prevents frost from forming below the cover 20.

[0094] The first ventilation portion 101 and the third ventilation portion 102 are arranged in parallel. Although the airflow directions are different, the airflow layers are parallel, which helps the moisturizing box 10 to be evenly stressed and reduces vibration caused by uneven airflow.

[0095] If the third ventilation part 102 is arranged vertically, it is impossible to ensure that the wind field in the moisturizing box 10 is uniform. In particular, after fresh food at room temperature is placed in the moisturizing box 10, hot and humid air rises and frost is easily formed locally on the top surface.

[0096] Optionally, the moisture-permeable cover plate 20 includes: a first plywood 201, which is configured with multiple first moisture-permeable holes 2011; a second plywood 202, which is configured with multiple second moisture-permeable holes 2021 and is detachably connected to the first plywood 201; a moisture-permeable membrane 203, which is located between the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021; wherein the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021 are arranged correspondingly.

[0097] The first clamping plate 201 and the second clamping plate 202 fix the moisture permeable membrane 203 and cooperate with the moisture permeable membrane 203 to more effectively adjust the humidity of the internal environment of the moisturizing box 10.

[0098] The second plywood 202 faces the moisturizing space within the moisturizing box 10, and the first plywood 201 is located above the second plywood 202. Water vapor within the moisturizing box 10 flows through the second moisture permeable holes 2021 to the moisture permeable membrane 203. Some of the water vapor passes through the moisture permeable membrane 203 and moves through the first moisture permeable holes 2011 to the top of the moisture permeable cover plate 20.

[0099] Optionally, a clamping groove is provided on the second clamping plate 202, and the moisture permeable membrane 203 is passed through the clamping groove. This helps to further improve the stability of the installation and fixation of the moisture permeable membrane 203.

[0100] The moisture-permeable membrane 203 operates by maintaining a humidity threshold. When the humidity inside the humidor 10 exceeds the threshold, the membrane 203 will permeate excess water vapor molecules to the outside of the humidor 10, that is, to the other side of the membrane 203 where the humidity is lower. When the humidity inside the humidor 10 is less than or equal to the threshold, the membrane 203 remains closed, and the permeation mode is disabled. The humidity on both sides of the membrane 203 does not affect each other.

[0101] For example, the moisture-permeable film may be a moisture-sensitive and moisturizing film, which can achieve the effects of moisturizing and moisture permeability by adjusting the intensity of the moisture permeability.

[0102] When the internal humidity is high and the external humidity is low, the internal adsorption is strong, the external dissipation is strong, and the conduction is strong, resulting in a moisture-permeable film. When the internal humidity is low, the adsorption is weak and the conduction is weak, resulting in a moisturizing film. High humidity results in strong adsorption, while low humidity results in weak adsorption. Large concentration differences or high humidity enhance conduction, while small concentration differences or low humidity weaken conduction. Low humidity results in strong dissipation, while high humidity results in weak dissipation.

[0103] Optionally, the ventilation area of ​​the first ventilation hole 1011 corresponding to the air outlet 501 of the cabinet 50 partially overlaps with the ventilation area of ​​the air outlet 501. This increases air flow efficiency and evenly distributes the cooling airflow while ensuring that frost does not condense above the moisture-permeable cover plate 20. Furthermore, overcooling caused by excessive airflow above the moisture-permeable cover plate 20 can be prevented. By partially overlapping the ventilation areas, the cooling capacity can be reduced.

[0104] Optionally, the storage basket is configured with an overlapping portion that overlaps the edge of the top opening of the cabinet body 50 for secure attachment. This overlapping portion not only allows the storage basket to be separated from other food items within the cabinet body 50, making them easier to manage and find, but also fully utilizes the overhead space, more effectively utilizing the vertical space of the refrigerator and increasing storage capacity. Furthermore, the storage basket fully utilizes the airflow from the air outlet 501 within the cabinet body 50, working in conjunction with the moisturizing box 10 and the moisture-permeable cover plate 20 to prevent frost and ice from forming on the surface of the moisture-permeable cover plate 20.

[0105] The disclosed embodiment also provides a storage basket, comprising: a quick-freezing box; a moisturizing box, which is arranged below the quick-freezing box and has a first ventilation portion configured on its side wall; wherein the quick-freezing box and the first ventilation portion are arranged to avoid each other, so as to prevent the bottom of the quick-freezing box from blocking the air circulation of the first ventilation portion, or the side wall of the quick-freezing box is configured with a second ventilation portion that matches the first ventilation portion, so that the second ventilation portion is connected to the first ventilation portion, and external air can flow into the moisturizing space in the moisturizing box through the second ventilation portion and the first ventilation portion. Through the moisturizing box and the quick-freezing box, the use function of the storage basket is increased, the space of the original storage basket with a single function is optimized, and the utilization rate is improved; air flows from the first ventilation portion through the moisturizing space in the moisturizing box, which can blow away some of the water vapor in the moisturizing box, avoiding frost on the top of the moisturizing box or the bottom of the quick-freezing box, thereby ensuring the humidity control effect of the moisturizing space in the moisturizing box.

[0106] The present disclosure also provides a refrigerator comprising a cabinet body 50 and a storage basket. The cabinet body 50 is open at the top; the storage basket is disposed above the cabinet body 50, with the edge of the storage basket overlapping the edge of the cabinet body 50 opening. The storage basket includes at least a moisturizing box 10, a quick-freezing box 30, and an expansion box 40. The moisturizing box 10 and the quick-freezing box 30 are stacked longitudinally, and the expansion box 40 semi-encloses the moisturizing box 10 in the transverse direction. The expansion box 40 and the moisturizing box 10 are movable relative to each other.

[0107] The refrigerator provided by the disclosed embodiment, through the use of the moisturizing box 10, the quick-freezing box 30, and the expansion box 40, adds the function of the storage basket. This optimizes the space of the original single-function storage basket and improves its utilization rate. During use, the quick-freezing box 30 can be taken up and down, and the expansion box 40 can be pulled out horizontally, making it convenient to use. In addition, the storage basket is connected to the top opening edge of the cabinet body 50 via an overlapping portion. This not only allows the storage basket to be separated from other food items in the cabinet body 50 for easier management and retrieval, but also fully utilizes the upper space, more effectively utilizing the vertical space of the refrigerator and increasing storage capacity.

[0108] The moisturizing box 10 defines a moisturizing space, the quick-freezing box 30 defines a quick-freezing space, and the expansion box 40 defines an expansion space with the side wall of the moisturizing box 10 after being pulled out of the moisturizing box 10 by a preset distance.

[0109] Optionally, the quick-freezing box 30 is partially or completely embedded in the moisturizing box 10 , and the expansion box 40 is a semi-open structure and is semi-enclosed outside the moisturizing box 10 .

[0110] The quick-freezing box 30 is partially or completely embedded in the moisturizing box 10, which not only helps to improve the stability of the connection between the quick-freezing box 30 and the moisturizing box 10; but also reduces the amount of air flowing through the moisture-permeable cover 20 in the moisturizing box 10, thereby ensuring the moisture control effect of the moisture-permeable cover 20.

[0111] When the quick-freezing box 30 is completely embedded in the moisturizing box 10 , it is possible to prevent the quick-freezing box 30 from affecting the closing of the refrigerator door and the cabinet body 50 .

[0112] The semi-open structure of the expansion box 40 can be understood as an open top and an open sidewall. The expansion box 40 is sleeved onto the exterior of the humidor 10 through the opening in the sidewall, thereby semi-enclosing the expansion box 40 outside the humidor 10. For example, one sidewall of the expansion box 40 along its length is open. That is, the expansion box 40 has only one longitudinal sidewall.

[0113] Optionally, it further includes: a moisture-permeable cover plate 20, which is arranged at the bottom of the quick-freezing box 30 and is located inside the moisturizing box 10.

[0114] The quick-freezing box 30 is placed on the moisturizing box 10 from top to bottom, and the moisture-permeable cover 20 is set at the bottom of the quick-freezing box 30. When the quick-freezing box 30 is taken out of the moisturizing box 10, the moisture-permeable cover 20 can be taken out of the moisturizing box 10 together, making it convenient for the user to directly take and put food in the moisturizing box 10.

In this way, the corresponding connection between the third ventilation portion 102 and the fifth ventilation portion 402 can prevent the side wall of the expansion box 40 from obstructing the third ventilation portion 102 and affecting airflow.

[0121] Optionally, the fifth ventilation portion 402 includes a plurality of fifth ventilation holes 4021 .

[0122] Optionally, the height difference between the center of the third ventilation portion 102 and the center of the air outlet 501 of the cabinet 50 is 20-40 mm. In this way, frost can be avoided while ensuring humidity control effect.

[0128] From top to bottom, the second overlapping portion 303, the first overlapping portion 104, and the third overlapping portion 404 are sequentially overlapped to form a hanging ear structure, which is overlapped with the opening edge of the cabinet body 50. This ensures not only the stability of the installation between the storage basket and the cabinet body 50, but also the stability of the assembly between the moisturizing box 10, the quick-freezing box 30, and the expansion box 40.

[0129] Optionally, the first overlapping portion 104 is formed on the width sidewalls of the moisturizing box 10, i.e., the first sidewall and the third sidewall. The first sidewall and the third sidewall of the moisturizing box 10 are respectively mounted to the opening edge of the cabinet 50 via the first overlapping portion 104.

[0131] Optionally, the depth of the step structure is greater than or equal to the thickness of the ear structure. In this way, when the ear structure is overlapped on the step structure, the cabinet door is covered to the top opening edge of the cabinet body 50, which can ensure the sealing between the cabinet door and the cabinet body 50.

[0132] An embodiment of the present disclosure provides a storage basket, comprising a moisturizing box 10 , a quick-freezing box 30 , and a moisture-permeable cover 20 .

[0133] The moisturizing box 10 is open at the top and has a first ventilation portion 101 on its side wall; the quick-freezing box 30 is arranged at the top of the moisturizing box 10 and has a second ventilation portion 301 on its side wall; the moisture-permeable cover 20 is arranged at the bottom of the quick-freezing box 30 and is located inside the moisturizing box 10; wherein the quick-freezing box 30 is embedded in the moisturizing box 10, and the second ventilation portion 301 is connected to the first ventilation portion 101, and the airflow flowing through the first ventilation portion 101 and the second ventilation portion 301 flows above the moisture-permeable cover 20.

[0134] The storage basket provided by the embodiment of the present disclosure increases the use function of the storage basket through the moisturizing box 10, the quick-freezing box 30 and the moisture-permeable cover 20 located between the two, optimizes the space of the original storage basket with a single function, and improves the utilization rate; the air flow flowing through the first ventilation part 101 and the second ventilation part 301 flows above the moisture-permeable cover 20, which can blow away the water vapor that passes through the moisture-permeable cover 20 in time, avoiding frost on the upper surface of the moisture-permeable cover 20, thereby ensuring the humidity control effect of the moisturizing space in the moisturizing box 10.

[0135] Optionally, the moisture-permeable cover 20 is detachably connected to the bottom of the quick-freezing box 30, which is convenient for replacing and maintaining the moisture-permeable cover 20, and a mezzanine space is defined between the moisture-permeable cover 20 and the quick-freezing box 30. The mezzanine space can be understood as a ventilation belt. The water vapor in the moisturizing space penetrates from the moisture-permeable cover 20 to the mezzanine space, and the mezzanine space is connected to the first ventilation part 101 and the second ventilation part 301; the air flow flows into the mezzanine space through the first ventilation part 101 and the second ventilation part 301, blowing the water vapor away from the top of the moisture-permeable cover 20, thereby preventing the water vapor from frosting on the upper surface of the moisture-permeable cover 20, thereby affecting the subsequent humidity control effect.

[0136] Optionally, the first ventilation portion 101 is disposed in a circumferential manner on the circumferential sidewall of the moisturizing box 10. Air flows in and out through the first ventilation portion 101, rapidly blowing moisture away from above the moisture-permeable cover plate 20. The second ventilation portion 301 is disposed in a circumferential manner on the circumferential sidewall of the quick-freezing box 30. The second ventilation portion 301 matches the first ventilation portion 101 to avoid affecting the air volume and air velocity of the first ventilation portion 101.

[0137] Optionally, the side wall of the humidifying box 10 is further configured with a third ventilation portion 102, and the airflow passing through the third ventilation portion 102 flows under the moisture-permeable cover plate 20. The airflow flows from the third ventilation portion 102 into the moisturizing space of the humidifying box 10 and flows under the moisture-permeable cover plate 20, which not only delivers cold air into the humidifying box 10 but also blows away liquid droplets or water vapor accumulated under the moisture-permeable cover plate 20, thereby preventing frost and ice from forming, which would affect the subsequent humidity control effect.

[0138] Optionally, the first ventilation slot 103 and the third ventilation portion 102 are respectively provided on different side walls of the moisturizing box 10. The third ventilation portion 102 is provided away from the air outlet 501 of the cabinet 50 to prevent excessive air volume and speed from blowing away moisture in the moisturizing space and affecting the moisturizing effect; while the first ventilation slot 103 is provided corresponding to the air outlet 501 to ensure the air volume and speed, thereby ensuring the quick freezing effect of the food in the quick freezing box 30.

[0139] Optionally, the bottom wall of the quick-freezing box 30 is higher than the second vent 301 to avoid the second vent 301. The bottom wall of the quick-freezing box 30 is configured with protruding ribs 306. Thus, the ribs 306 separate the bottom wall of the quick-freezing box 30 from the stored food, preventing the food in the quick-freezing box 30 from adhering to the bottom wall of the quick-freezing box 30, which would affect air flow at the bottom and thus the quick-freezing effect.

[0140] Optionally, a bottom ventilation slot is formed on the bottom wall of the quick-freezing box 30 , and the bottom ventilation slot is communicated with an interlayer space defined between the moisture-permeable cover plate 20 and the quick-freezing box 30 .

[0141] Water vapor that penetrates the interlayer space through the moisture-permeable cover plate 20 can continue to move upward and through the bottom ventilation slots to the quick-freezing space, thereby increasing the humidity of the food in the quick-freezing space. In addition, when the cold air flows through the interlayer space, part of the cold air flow diffuses into the bottom ventilation slots, cooling and quickly freezing the food at the bottom of the quick-freezing box 30, thereby improving the overall quick-freezing efficiency of the quick-freezing box 30.

[0142] Optionally, the moisture-permeable cover 20 includes: a first splint 201, which is configured with a positioning portion 2012; a second splint 202, which is configured with a snap-fit ​​portion 2022 and is detachably connected to the first splint 201; a moisture-permeable membrane 203, which is arranged between the first splint 201 and the second splint 202; wherein, the bottom of the quick-freezing box 30 is configured with a positioning fitting portion 304 and a snap-fit ​​fitting portion 305, the positioning portion 2012 of the first splint 201 is connected to the positioning fitting portion 304, and the snap-fitting portion 2022 of the second splint 202 is connected to the snap-fitting portion 305.

[0143] The first splint 201 and the second splint 202 are detachably connected. Then, the first splint 201 is connected to the positioning matching portion 304 of the quick-freezing box 30 through the positioning portion 2012 to realize the positioning and installation of the first splint 201 and the quick-freezing box 30. After determining the position of the first splint 201, the snap-fit ​​portion 2022 of the second splint 202 is connected to the snap-fitting portion 305 of the quick-freezing box 30 to realize the detachable connection between the moisture-permeable cover 20 as a whole and the quick-freezing box 30.

[0144] The moisture-permeable cover plate 20 is dually positioned by the positioning portion 2012 and the clamping portion 2022 to ensure its proper installation within the quick-freezing box 30. This also prevents the moisture-permeable cover plate 20 from being reversely assembled, which would affect moisture permeability. The first clamping plate 201 faces the bottom wall of the quick-freezing box 30.

[0145] The positioning portion 2012 may be a groove structure, and the positioning matching portion 304 may be a protrusion structure. Alternatively, the positioning portion 2012 may be a protrusion structure, and the positioning matching portion 304 may be a groove structure.

[0146] Optionally, the moisturizing box 10 is configured with a first overlapping portion 104, and the quick-freezing box 30 is configured with a second overlapping portion 303; wherein the second overlapping portion 303 overlaps the first overlapping portion 104 and matches the first overlapping portion 104. The first overlapping portion 104 and the second overlapping portion 303 enable the moisturizing box 10 and the quick-freezing box 30 to be assembled. The second overlapping portion 303 overlapping the first overlapping portion 104 not only facilitates the removal and placement of the quick-freezing box 30, but also allows the moisturizing box 10 to be transported together with the quick-freezing box 30.

[0147] The embodiment of the present disclosure further provides a moisturizing assembly, comprising: a moisturizing box 10 and a moisture permeable cover plate 20. The moisturizing box 10 with the moisture permeable cover plate 20 has a humidity control function.

[0148] The moisturizing box 10 has an open top and a side wall with at least a first ventilation portion 101 and a third ventilation portion 102 arranged side by side along the depth direction of the moisturizing box 10; a moisture-permeable cover plate 20 covers the opening of the moisturizing box 10 and is located between the first ventilation portion 101 and the third ventilation portion 102.

[0149] Using the moisturizing component provided in the embodiment of the present disclosure, food is placed in the moisturizing space in the moisturizing box 10, and the moisture-permeable cover 20 is covered on the opening of the moisturizing box 10 to adjust the humidity of the moisturizing space; through the first ventilation part 101 and the second ventilation part 301, air flows through the top and bottom of the moisture-permeable cover 20, quickly blowing the leaked water vapor and the accumulated water vapor away from the moisture-permeable cover 20, preventing the moisture-permeable cover 20 from frosting and affecting the subsequent humidity control effect.

[0150] Optionally, third ventilation portions 102 are provided on two opposing side walls of the humidor 10 to provide opposite-side ventilation. This, on the one hand, controls the amount of air flowing into the humidor 10, preventing excessive airflow that would blow away most of the moisture within the humidor 10, thereby reducing humidity within the humidor 10 and affecting the moisturizing effect of the food. On the other hand, the incoming cold airflow cools the food, ensuring that the food remains frozen.

[0151] Optionally, the moisture-permeable cover 20 is located in the moisturizing box 10 and divides the internal space of the moisturizing box 10 into an upper cavity and a lower cavity; wherein the first ventilation portion 101 is connected to the upper cavity, and the third ventilation portion 102 is connected to the lower cavity.

[0152] The interior of the humidor 10 is divided by a moisture-permeable cover 20. Water vapor in the lower cavity flows through the moisture-permeable cover 20 and overflows into the upper cavity. Airflow through the first ventilation section 101, after passing through the upper cavity, blows away moisture from the upper cavity, preventing frost from forming there. Airflow through the third ventilation section 102 flows into the lower cavity, cooling the food inside. This not only ensures the food is frozen effectively but also blows away moisture from beneath the moisture-permeable cover 20, preventing condensation on the lower surface of the cover 20, which could affect subsequent moisture penetration and, consequently, humidity regulation.

[0153] Optionally, the side wall of the moisturizing box 10 is further configured with a first ventilation slot 103 , which is located above the first ventilation portion 101 , and a ventilation area of ​​the first ventilation slot 103 is greater than a ventilation area of ​​the first ventilation portion 101 .

[0154] The first ventilation slots 103 are located above the first ventilation portion 101, and their ventilation area is larger than that of the first ventilation portion 101. This helps the cold air from the first ventilation slots 103 quickly cool the upper cavity, thereby quickly freezing the food. Furthermore, the cold air from the first ventilation portion 101 quickly removes moisture from the upper surface of the moisture-permeable cover plate 20, preventing frost from forming on the upper surface.

[0155] Optionally, first ventilation slots 103 are provided on two opposing side walls of the humidor 10 to provide opposite-side ventilation. Opposite-side ventilation is cross-flow ventilation, where air flows in from one side and out from the opposite side. This helps ensure that air flows through the entire upper cavity, preventing it from flowing outward in all directions, thereby ensuring the quick freezing of food in the upper cavity.

[0156] Optionally, the first ventilation portion 101 includes a plurality of first ventilation holes 1011, and the third ventilation portion 102 includes a plurality of third ventilation holes 1021; wherein the first ventilation holes 1011 and the third ventilation holes 1021 located on the same side wall of the moisturizing box 10 are staggered or correspondingly arranged.

[0157] When the first ventilation hole 1011 and the third ventilation hole 1021 are staggered on the same side wall of the moisturizing box 10, the structural strength of the side wall is ensured and its service life is improved. When the first ventilation hole 1011 and the third ventilation hole 1021 are arranged correspondingly on the same side wall of the moisturizing box 10, the force applied to the same position of the side wall is uniform.

[0158] The present disclosure also provides a storage basket, comprising a moisturizing box 10 and an expansion box 40. By pulling the expansion box 40, the expansion box 40 moves relative to the moisturizing box 10, thereby releasing expansion space to store more food.

[0159] The moisturizing box 10 is open at the top; the expansion box 40 is a semi-open structure, and the expansion box 40 can be semi-enclosed outside the moisturizing box 10; wherein, the expansion box 40 and the moisturizing box 10 can enclose a storage cavity, and the volume of the storage cavity is controlled by the distance between the expansion box 40 and the moisturizing box 10 in the lateral movement direction.

[0160] The storage basket provided in the disclosed embodiment can be expanded by pulling the expansion box 40 laterally, allowing it to move relative to the humidor 10, thereby adjusting the volume of the storage cavity and expanding the storage space of the basket. This not only allows for more food storage but also allows for the separation of different food items. When expansion is not needed, the humidor 10 and expansion box 40 can be stacked together, reducing space usage and providing ease of use to meet the diverse needs of users.

[0161] Optionally, the expansion box 40 is semi-enclosed from the bottom and side of the moisturizing box 10 to the outside of the moisturizing box 10. In this way, not only can the expansion box 40 be pulled out, but also when the expansion box 40 is pulled out horizontally, a side wall of the moisturizing box 10 can be used as the missing side wall of the expansion box 40, that is, a side wall of the moisturizing box 10 and the expansion box 40 together enclose a storage cavity.

[0162] Optionally, the depth of the expansion box 40 is greater than or equal to the depth of the moisturizing box 10. In this way, when the expansion box 40 expands the storage space, the volume of the storage space can be increased, further improving the space utilization of the storage basket in the cabinet 50 and enhancing the user experience.

[0163] Optionally, the moisturizing box 10 is configured with a first overlapping portion 104, and the expansion box 40 is configured with a third overlapping portion 404; the first overlapping portion 104 and the third overlapping portion 404 are arranged to abut against each other. The first overlapping portion 104 and the third overlapping portion 404 facilitate assembly of the moisturizing box 10 and the expansion box 40. The moisturizing box 10 and the expansion box 40 can be transported and installed as a single unit, making it quick and convenient.

[0164] Optionally, the first overlapping portion 104 is configured with a positioning groove 1041 , and the third overlapping portion 404 is configured with a positioning protrusion 4041 . The positioning protrusion 4041 is embedded in the positioning groove 1041 and can slide along the positioning groove 1041 to limit the movement trajectory of the expansion box 40 .

[0165] The first overlapping portion 104 and the third overlapping portion 404 are precisely positioned and limited by the positioning groove 1041 and the positioning protrusion 4041. In particular, when the expansion box 40 is pulled horizontally to expand the space, the positioning groove 1041 and the positioning protrusion 4041 can limit the movement trajectory of the expansion box 40.

[0166] Optionally, the side wall of the expansion box 40 is constructed with a fifth ventilation portion 402 , which is arranged corresponding to the third ventilation portion 102 of the moisturizing box 10 , and the ventilation area of ​​the fifth ventilation portion 402 is less than or equal to the ventilation area of ​​the third ventilation portion 102 .

[0167] When the expansion box 40 and the moisturizing box 10 are superimposed on each other, the airflow outside the storage basket flows through the fifth ventilation part 402 and the third ventilation part 102 in sequence and flows into the moisturizing box 10; wherein, when the ventilation area of ​​the fifth ventilation part 402 is smaller than the ventilation area of ​​the third ventilation part 102, the airflow rate flowing into the moisturizing box 10 is adjusted by the overlapping of the fifth ventilation part 402 and the third ventilation part 102, thereby adjusting the humidity and cooling rate in the moisturizing box 10 to meet the storage requirements of specific ingredients.

[0168] When the expansion box 40 is pulled out horizontally to form an expansion space, cold air outside the storage basket flows into the expansion space through the fifth ventilation portion 402, which can cool the food in the expansion space and ensure the freezing effect of the food.

[0169] Optionally, the fifth ventilation portion 402 is located on a side wall of the expansion box 40 that overlaps with the moisturizing box 10. The fifth ventilation portion 402 is provided corresponding to the third ventilation portion 102 and is located on a side wall of the expansion box 40 that overlaps with the moisturizing box 10 to ensure connectivity with the third ventilation portion 102, thereby avoiding affecting humidity control within the moisturizing box 10.

[0170] The embodiment of the present disclosure further provides a refrigerator, comprising a cabinet body 50 and a moisturizing box 10 .

[0171] An air outlet is constructed on the inner side wall of the cabinet body 50; the moisturizing box 10 is arranged in the cabinet body 50, and the moisturizing box 10 defines a moisturizing space, and the side wall is constructed with a moisturizing air outlet connected to the moisturizing space; wherein, the moisturizing air outlet and the air outlet are arranged to avoid each other, and / or, the plane where the moisturizing air outlet is located intersects with the plane where the air outlet is located.

[0172] In the refrigerator provided by the disclosed embodiment, the moisturizing box 10 is located within the cabinet body 50 to moisturize the stored food and maintain its freshness. By designing a configuration where the moisturizing vents and the air outlets are offset from each other and the planes on which the moisturizing vents lie intersecting with the planes on which the outlets lie, it is possible to prevent airflow from the outlets from passing directly into the moisturizing space through the moisturizing vents, causing moisture to be released from the food surface, reducing the food's humidity and thus affecting the food's taste.

[0173] Optionally, the refrigerator further comprises: a moisture permeable cover plate, which is arranged on the top of the moisturizing box 10 and is located above the moisturizing air vent. The moisturizing air vent here can be equivalent to the third ventilation part 102 in this article.

[0174] Optionally, the moisturizing vent is arranged to avoid the air outlet to prevent the air flow from the air outlet from blowing directly to the moisturizing vent. Exemplarily, the moisturizing vent is not arranged directly opposite the air outlet, or the edge of the moisturizing vent avoids the edge of the air outlet and the air outlet area defined by it.

[0175] The return air vent of the cabinet 50 is located at the bottom, and the airflow from the air outlet on the side corresponding to the return air vent blows straight forward and then flows into the return air vent; while the airflow from other air outlets flows forward and to one side and then flows into the return air vent.

[0176] In this embodiment, the moisturizing box 10 can be arranged on the side where the return air outlet is located, and the moisturizing air outlet is arranged to avoid the air outlet. The air outlet here can be the first air outlet 5011 mentioned in this article.

[0177] The moisturizing box 10 is arranged in the upper space of the cabinet 50 , which is convenient for assembly on the one hand and helps to improve the space utilization rate in the cabinet 50 on the other hand.

[0178] Optionally, the edge of the air outlet is configured with air guide ribs 5012 to guide the air flow; and / or, the edge of the air outlet is configured with air guide ribs 5012 arranged obliquely upward along the air outlet direction. The guide ribs ensure the flow direction of the air flow blown out of the air outlet.

[0179] Optionally, the air circulation volume of the moisturizing space is M=Q1 / V, and 1≤M≤2.5; wherein Q1 is the air volume in the moisturizing box 10, and V is the volume of the moisturizing space formed in the moisturizing box 10.

[0180] For example, the volume of the moisturizing space in the moisturizing box 10 is about 10L, and the humidity therein is affected by two factors: first, the amount of water vapor emitted by the food itself; second, the amount of water vapor taken away by the air volume entering the moisturizing space and the moisture permeable membrane 203; the amount of water vapor taken away by the second moisture permeable membrane 203 is considered separately, and here only the moisturizing air outlet area is increased to verify the effect of air volume, which are 5 / 10 / 15 / 20 / 25 / 30L / min respectively. The amount of water vapor emitted by the food itself is represented by the volume ratio of ice cubes placed in it, which are 5%, 25%, 50%, 75%, and 100% respectively; the humidity at the center of the moisturizing space is tested.

[0181]

[0182] It can be seen from the above test data that when the air circulation volume (i.e., air volume / volume) of the moisturizing space is small, the humidity in the moisturizing box 10 cannot be discharged in time. Affected by the moisture-permeable membrane 203, the center still maintains 90%, but frost has appeared on the front side wall; when the air circulation volume of the moisturizing space is large, the humidity in the moisturizing box 10 is low, especially when there is less food in the box.

[0183] Therefore, the air circulation rate of the moisturizing space (ie, the ratio of the air volume in the moisturizing box 10 to the volume of the moisturizing space) is preferably between 1 and 2.5. This can not only maintain the moisturizing effect but also prevent frost.

[0184] Optionally, the air volume Q1 in the moisturizing box 10 is S*F, where S is half of the total ventilation area of ​​the moisturizing air outlet, and F is the wind speed of the circulating air flow in the cabinet 50, and the value range of F is 0.05 to 0.2 m / s.

[0185] The airflow within the cabinet 50 includes direct airflow and circulating airflow. The direct airflow is blown directly out of the air outlet and passes through guide channels such as the air guide ribs 5012 and the door village. Its wind speed is less affected by distance and has a wind speed of 0.5 to 3 m / s. It is the main source of cooling capacity. The circulating airflow is partly dissipated directly by the direct airflow, and the other part is generated by the air flow movement inside the cabinet driven by the direct airflow. The wind speed is 0.05 to 0.2 m / s, which assists in cooling the cabinet. The average wind speed of the circulating airflow is 0.05 to 0.2 m / s. The wind speed of the circulating airflow varies little at different locations in the cabinet, so the ventilation area of ​​the moisturizing space air outlet basically determines the air volume entering the moisturizing space.

[0186] Optionally, the refrigerator further includes a quick-freezing box 30 disposed above the moisturizing box 10. The quick-freezing box 30 defines a quick-freezing space, and a quick-freezing air vent is provided on a side wall of the quick-freezing box 30, communicating with the quick-freezing space. The quick-freezing air vent herein may be equivalent to the second ventilation slot 302 herein.

[0187] Optionally, the quick-freezing box 30 is located above the moisture-permeable cover plate, defining a mezzanine space between the quick-freezing box 30 and the moisture-permeable cover plate. The sidewalls of the quick-freezing box 30 and / or the moisturizing box 10 are configured with anti-frost vents connected to the mezzanine space, allowing air to flow into the mezzanine space and prevent frost from forming above the moisture-permeable cover plate. The anti-frost vents herein may correspond to the first ventilation portion 101 herein. Optionally, the anti-frost vents are provided corresponding to the air outlets.

[0188] Optionally, the number of air circulation times per minute in the quick-freezing space should be greater than 5 times, and the corresponding air volume should be greater than 12.15L / min.

[0189] The embodiment of the present disclosure also provides a refrigerator, which includes a cabinet body 50 and a door body 60; a moisturizing box 10 is arranged in the cabinet body 50, and the moisturizing box 10 defines a moisturizing space, and the side wall is constructed with a moisturizing air vent connected to the moisturizing space; wherein, along the depth direction of the cabinet body 50, the moisturizing air vent is separated from the inner wall of the door body 60 by a first preset distance.

[0190] In the refrigerator provided by the disclosed embodiment, the moisturizing box 10 is located within the cabinet body 50 to moisturize the stored food and maintain its freshness. Along the depth direction of the cabinet body 50, the moisturizing vents are spaced a first predetermined distance from the inner wall of the door body 60. This prevents cold air flowing through the inner wall of the door body 60 from directly flowing into the moisturizing space through the moisturizing vents, which could cause moisture to precipitate from the surface of the food, reducing its humidity and thus affecting its taste. The refrigerator not only has a freezing function, but also simultaneously provides moisturizing and fresh-keeping functions.

[0191] Optionally, a first preset distance between the moisturizing air vent and the inner wall of the door body 60 is greater than 60 mm.

[0192] In practice, the direct airflow from the air outlet flows along the guide groove 601 on the inner wall of the door 60 toward the other side of the cabinet 50. This means that the direct airflow from the air outlet flows along the inner wall of the door 60. The wind speed varies at different locations relative to the inner wall of the door 60. The relevant data is shown in the table below.

[0193]

[0194] As can be seen, when the distance from the inner wall of the door body 60 is greater than 55 mm, the airflow speed is significantly reduced, so this position is less affected by the direct airflow. Therefore, designing the first preset distance between the moisturizing air vent and the inner wall of the door body 60 to be greater than 60 mm can better ensure that the moisturizing air vent avoids the influence of the direct airflow from the air outlet, ensuring the moisturizing effect in the moisturizing space.

[0195] It should be noted that the measurement point of the first preset distance between the moisturizing air vent and the inner wall of the door body 60 can be the lower edge of the moisturizing air vent or the center point of the moisturizing air vent.

[0196] Optionally, the inner wall of the cabinet 50 is configured with a plurality of air outlets, and the moisturizing air outlets are arranged to avoid the air outlets. In this way, it is possible to prevent the cold air blown out from the air outlets from blowing directly into the moisturizing air outlets and entering the moisturizing space, thereby affecting the moisturizing effect of the food in the moisturizing space.

[0197] Optionally, the refrigerator further comprises: a quick-freezing box 30, which is arranged above the moisturizing box 10, and the quick-freezing box 30 defines a quick-freezing space; wherein, the quick-freezing box 30 is spaced from the inner wall of the door body 60 by a second preset distance.

[0198] The quick-freezing box 30 is located above the moisturizing box 10 and closer to the inner wall of the door 60. The quick-freezing box 30 can rapidly cool the food in the quick-freezing space by means of the direct airflow flowing through the inner wall of the door 60, thereby achieving the purpose of quick freezing. In order to ensure smooth flow of air between the cabinet 50 and the door 60, and to ensure air circulation within the cabinet 50, the quick-freezing box 30 is separated from the inner wall of the door 60 by a second predetermined distance. This distance not only ensures smooth air circulation within the cabinet 50, but also fully utilizes the cooling effect of the direct airflow flowing through the inner side of the door 60, thereby achieving rapid freezing of the food in the quick-freezing box 30.

[0199] Optionally, the second preset distance between the quick-freezing box 30 and the inner wall of the door body 60 is less than 55 mm.

[0200] Based on the experimental data in the table above for different wind speeds at different locations from the inner wall of the door 60, the second preset distance between the quick-freezing box 30 and the inner wall of the door 60 is set to be less than 55 mm. This ensures smooth air circulation within the cabinet 50 and fully utilizes the cooling effect of the direct airflow passing through the inner side of the door 60 to quickly freeze the food in the quick-freezing box 30.

[0201] It should be noted that the measurement point of the second preset distance between the quick-freezing box 30 and the inner wall of the door body 60 may be the bottom wall of the quick-freezing box 30 or the center point of the quick-freezing space defined by the quick-freezing box 30 .

[0202] Optionally, a quick freezing air vent is provided on the side wall of the quick freezing box 30 and is connected to the quick freezing space. The quick freezing air vent is corresponding to the air outlet of the cabinet 50. The cold air directly blown out of the air outlet of the cabinet 50 flows into the quick freezing space through the quick freezing air vent, cooling the food in the quick freezing space and achieving the purpose of quick freezing.

[0203] Optionally, the quick-freezing box 30 is embedded in the top of the moisturizing box 10, and the side wall of the moisturizing box 10 is configured with ventilation slots that match the quick-freezing air outlet. In this way, the air blown out of the air outlet passes through the ventilation slots and flows into the quick-freezing space through the quick-freezing air outlet, cooling and quick-freezing the food in the quick-freezing space.

[0204] The disclosed embodiment further provides a moisturizing assembly, including a moisturizing box 10 and a moisture permeable module.

[0205] The moisturizing box 10 is defined as having a storage space; the moisture permeable module is provided in the moisturizing box 10 and divides the storage space into a plurality of moisturizing spaces; wherein the side wall of the moisturizing box 10 is constructed with moisturizing vents matching the moisturizing spaces.

[0206] By using the moisturizing component provided in the embodiment of the present disclosure, the storage space in the moisturizing box 10 is divided into multiple moisturizing spaces through a moisture-permeable module. Each moisturizing space is matched with a moisturizing air outlet to achieve zoned humidity control, meet diverse storage needs, and ensure the freezing moisturizing effect in each moisturizing space.

[0207] Optionally, the moisture permeable module includes multiple moisture permeable cover plates, which divide the storage space into multiple moisturizing spaces. The multiple moisturizing spaces can achieve different humidity control, thereby achieving zoned humidity control.

[0208] Optionally, multiple moisture-permeable cover plates are arranged side by side, which facilitates installation and better determines the volume of the moisturizing space for storing food.

[0209] Optionally, the plurality of moisture permeable cover plates are arranged in parallel transversely, and / or the plurality of moisture permeable cover plates are arranged in parallel longitudinally.

[0210] For example, in the case of three moisture permeable cover plates, the three moisture permeable cover plates are arranged in an upper, middle and lower structure, and three moisture-retaining spaces are defined by the three moisture permeable cover plates and the moisturizing box 10. Optionally, the performance parameters of the moisture permeable membranes 203 of the three moisture permeable cover plates are inconsistent.

[0211] For example, the humidity in the bottom moisturizing space is controlled to 85% through the cooperation of the moisturizing vents and the moisture-permeable membrane 203. Excess moisture vapor is transferred to the moisturizing space in the upper (middle) layer. The volume of the middle moisturizing space 200 is the same as that of the bottom moisturizing space. However, the moisture permeability of the moisture-permeable membrane 203 of the moisture-permeable cover plate above the middle moisturizing space 200 is higher than that of the moisture-permeable membrane 203 above the bottom moisturizing space 300. Furthermore, the ventilation area of ​​the moisturizing vents corresponding to the middle moisturizing space 200 is larger than that of the moisturizing vents corresponding to the bottom moisturizing space 300. This is done to further reduce the existing humidity in the middle moisturizing space 200. Assuming the humidity in the middle moisturizing space 200 reaches 60%, excess moisture vapor is transferred to the upper (top) moisturizing space.

[0212] The top moisturizing space 100 has the same volume as the bottom moisturizing space 300 and the middle moisturizing space 200. However, the moisture permeability of the moisture-permeable membrane 203 above the top moisturizing space 100 is higher than that of the middle moisturizing space 200. Furthermore, the ventilation area of ​​the moisturizing vents corresponding to the top moisturizing space 100 is larger than that of the middle moisturizing space 200. This is done to further reduce the existing humidity within the top moisturizing space 100. Assume that the humidity in the top moisturizing space 100 reaches 45%.

[0213] When dynamic equilibrium is reached, the humidity in each moisturizing space tends to be stable, which does not mean that water vapor conduction does not occur, but it is a dynamic equilibrium process.

[0214] It should be noted that the location of the three-layer moisturizing space is not limited to a top-center-bottom structure; it can also be a left-center-right structure or a front-center-back structure. Regardless of the left-center-right structure or the front-center-back structure, the principle of achieving zoned humidity control with multiple moisture-permeable cover panels is the same as that of achieving zoned control with a top-center-bottom structure.

[0215] When the three moisturizing spaces have the same volume but use different moisture-permeable membranes 203, the areas of the ventilation holes are different. The higher the relative position of the moisturizing space, the larger the area of ​​the corresponding moisturizing vent should be, to ensure that the humidity in the moisturizing space is maintained within a stable range. This ensures that the humidity in the three moisturizing spaces is transferred in a step-by-step manner.

[0216] Optionally, the moisture permeability of the multiple moisture permeable cover plates may be partially or entirely the same. In this way, the humidity conditions of the moisturizing spaces corresponding to different moisture permeable cover plates are different, thereby being able to store food with different humidity requirements, meeting the different needs of users and improving the user experience.

[0217] Optionally, when the multiple moisture permeable cover plates are arranged in parallel laterally, the moisture permeabilities of the multiple moisture permeable cover plates gradually increase from bottom to top.

[0218] In this way, when there are multiple stacked moisturizing spaces, the multiple moisture-permeable cover plates have different moisture permeabilities. The moisture-permeable membrane 203 on the bottom layer can be used to conduct moisture upward to the moisturizing space above it, thereby humidifying the moisturizing space above it. In this way, using multiple layers of moisture-permeable membrane 203, the purpose of zoned humidity control is achieved within the moisturizing box 10.

[0219] Optionally, multiple sets of moisturizing vents matching multiple moisturizing spaces may have some or all of the same ventilation area. Moisturizing vents with different ventilation areas, combined with a breathable cover, enable humidity control in different moisturizing spaces, thereby storing ingredients with varying humidity requirements, meeting the diverse needs of users and enhancing the user experience.

[0220] Optionally, when multiple moisture-permeable cover plates are arranged in parallel laterally, the ventilation areas of the multiple groups of moisturizing air vents gradually increase from bottom to top.

[0221] In this way, the volumes of the three moisturizing spaces are the same, but the moisture permeable membranes 203 used are different. The areas of the ventilation holes are different. The higher the relative position of the moisturizing space is, the larger the area of ​​the corresponding moisturizing vents should be, so as to ensure that the humidity in the moisturizing space is maintained within a stable range. This ensures that the humidity in the three moisturizing spaces is transferred in a step-by-step manner.

[0222] The disclosed embodiment further provides a moisturizing assembly, comprising: a moisturizing box 10 and a moisture-permeable cover.

[0223] The moisture-permeable cover is provided on the moisturizing box 10, and defines a moisturizing space together with the moisturizing box 10; wherein, the moisture-permeable cover includes a connected plywood and a moisture-permeable membrane 203, and the area of ​​the moisture-permeable membrane 203 and the volume of the moisturizing space meet the first condition, and / or the area of ​​the moisture-permeable membrane 203 and the area of ​​the plywood meet the second condition.

[0224] By using the moisturizing component provided in the embodiment of the present disclosure, the humidity in the moisturizing space is adjusted through the moisture-permeable cover plate, and the area of ​​the moisture-permeable membrane 203 and the volume of the moisturizing space are adjusted to meet the first condition, and / or the area of ​​the moisture-permeable membrane 203 and the area of ​​the plywood are adjusted to meet the second condition, thereby ensuring that the humidity in the moisturizing box 10 meets the requirements and improving the preservation effect of the food.

[0225] Optionally, the area Sm of the moisture permeable membrane 203 and the volume V of the moisturizing space satisfy a first condition: Sm=V*C; wherein C is a moisture permeability area coefficient, and the value range of C is 1.90% to 3.00%.

[0226] The experimental data related to the area of ​​the moisture permeable membrane 203, the volume of the moisturizing space, and the moisture permeability of the moisture permeable membrane 203 are as follows:

[0227] <![CDATA[Moisture Permeable Membrane Area / cm 2 > <![CDATA[Moisture retention space volume / cm 3 > Moisture permeability / % humidity / % 245 10000 95％ 87.01％ 240 10000 95％ 84.67％ 280 14400 95％ 83.70％ 235 10000 95％ 83.23％ 250 10000 95％ 82.99％ 275 14400 95％ 82.36％ 260 10000 95％ 81.19％ 255 10000 95％ 80.67％ 270 14400 95％ 79.94％ 255 14400 95％ 79.58％ 260 14400 95％ 74.31％

[0228] The moisture permeability coefficient C ranges from 1.90% to 3.00%. At this time, the humidity in the moisturizing box 10 is greater than or equal to 80%.

[0229] When the moisture permeability coefficient is less than 1.90%, the humidity inside the moisturizing box 10 cannot reach 80%. This data shows that there is a certain quantitative relationship between the area of ​​the moisture permeable membrane 203 and the volume of the moisturizing space. For example, if the volume of the moisturizing space is 10,000 cm3, the area of ​​the moisture permeable membrane 203 should be between 235-260 cm2 to meet the humidity requirement.

[0230] Optionally, the area Sm of the moisture-permeable membrane 203 and the area of ​​the plywood Sg satisfy the second condition: 0.30Sg ≤ Sm ≤ 0.57Sg. This ensures that the humidity within the humidor 10 meets the required level while also preventing frost from forming. It should be noted that the plywood area here refers to the area of ​​a single surface.

[0231] When the area of ​​the moisture permeable film 203 and the area of ​​the clamping plate meet the second condition, it helps to improve the utilization rate of the moisture permeable film 203 and reduce production costs.

[0232] The results of the effect of the area of ​​the moisture permeable membrane 203 and the area of ​​the plywood on the humidity of the moisturizing space are detailed in the table below.

[0233] <![CDATA[Moisture Permeable Membrane Area S m > 20000 23000 26000 29000 32000 35000 <![CDATA[The splint area S g > 66946 66946 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 30％ 34％ 39％ 43％ 48％ 52％ humidity 85% - Cream 84％ 84％ 83％ 83％ 82％ <![CDATA[Moisture permeable membrane area S m > 38000 41000 44000 47000 50000 53000 <![CDATA[The splint area S g > 66946 66946 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 57％ 61％ 66％ 70％ 75％ 79％ humidity 81％ 80％ 79％ 75％ 70％ 69％ <![CDATA[The area S of the moisture-permeable membrane m > 56000 59000 62000 66946 <![CDATA[Splint area S g > 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 84％ 88％ 93％ 100％ humidity 68％ 68％ 67％ 65％

[0234] As can be seen from the table above, the relationship between Sm and Sg is 0.30Sg ≤ Sm ≤ 0.57Sg. At this point, the humidity inside the humidifying box 10 meets the requirements, and no frost is observed. When the ratio of Sm to Sg is less than 0.30, although the humidity inside the humidifying box 10 exceeds 80%, due to the small area of ​​the moisture-permeable membrane 203, water vapor easily accumulates when it penetrates through the moisture-permeable membrane 203 to the top of the moisturizing cover. Over time, condensation and frosting will occur. When the ratio of Sm to Sg is greater than 0.57, the humidity inside the humidifying box 10 does not reach 80%. The main reason is that the moisture-permeable area is too large, and too much water vapor penetrates through the moisture-permeable membrane 203 to the top of the moisturizing cover.

[0235] Optionally, the plywood includes: a first plywood 201 having a plurality of first moisture-permeable holes 2011; and a second plywood 202 having a plurality of second moisture-permeable holes 2021 and detachably connected to the first plywood 201. The first moisture-permeable holes 2011 and the second moisture-permeable holes 2021 are arranged in correspondence with each other, and the moisture-permeable membrane 203 is located between the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021. The plywood herein consists of the first plywood 201 and the second plywood 202. When calculating the plywood area, only the plywood area of ​​the first plywood 201 or the second plywood 202 is calculated (i.e., the area of ​​a single-sided plywood is calculated).

[0236] Optionally, the ratio of the air volume of the quick-freezing space to the air volume of the moisturizing space is in the range of 10 to 20.

[0237] The storage basket is placed at the opening of the cabinet body 50. Part of the cold air blown out from the air outlet of the freezer enters the quick-freezing space through the quick-freezing air outlet, and part of it flows into the interlayer space above the moisture-permeable cover through the anti-frost air outlet (first ventilation part 101). The circulating air flow in the cabinet flows into the moisturizing space through the moisturizing air outlet (third ventilation part 102).

[0238] The cold air entering the quick-freezing space must ensure that the food in the quick-freezing space is quickly frozen. In principle, the greater the air volume entering the quick-freezing space, the better the effect of the quick-freezing space. The role of the air volume above the moisture-permeable cover is as follows: the water vapor in the moisturizing space penetrates into the interlayer space above the moisture-permeable cover through the moisture-permeable membrane 203. If the water vapor is not taken away in time, it will frost above the moisture-permeable cover due to the temperature being lower than the dew point, which reduces the effect of the moisture-permeable membrane 203. The cold air in the moisturizing box 10 has two functions. One is to bring the water vapor in the moisturizing box 10 to the outside of the moisturizing box 10 to prevent the water vapor from contacting the inner wall of the moisturizing box 10 for a long time and causing condensation to frost; the second is to provide a power for the moisture-permeable membrane 203. Through the circulation of air volume, the water vapor continuously passes through the moisture-permeable membrane 203 to ensure the stability of the humidity in the moisturizing box 10.

[0239] The air volume distribution in the quick-freezing space and above the moisture-permeable cover is interrelated. Once the air volume in the quick-freezing space is determined, the air volume in the mezzanine space above the moisture-permeable cover can be confirmed.

[0240] In this embodiment, six schemes for the air volume of the quick-freezing space and the air volume of the moisturizing space are given for experimentation. The relevant experimental data and results are shown in the following table.

[0241] Solution 1: The air volume of the quick-freezing space is 110L / min, the air volume of the moisturizing space is 13.4L / min, the moisturizing box is 10, and the moisture-permeable cover has uniform flow lines and can cover the entire area inside the box.

[0242] Solution 2: The air volume of the quick-freezing space is 76.5L / min, and the air volume of the moisturizing space is 9.4L / min. The streamlines of the moisturizing box 10 are uneven, and the air volume cannot fully cover the entire area inside the box, posing a risk of frost. The flow field of the moisture-permeable plate is uniform.

[0243] Solution 3: The air volume of the quick-freezing space is 42.1L / min, and the air volume of the moisturizing space is 18.9L / min. The streamlines of the moisturizing box 10 and the moisture-permeable cover are uneven, and the air volume cannot fully cover the entire area, resulting in a great risk of frost.

[0244] Solution 4: The air volume of the quick-freezing space is 189.9L / min, and the air volume of the moisturizing space is 8.8L / min. The streamlines of the moisturizing box 10 are uneven, and the air volume cannot fully cover the entire area inside the box, posing a risk of frost. The flow field of the moisture-permeable cover is uniform.

[0245] Solution 5: The air volume of the quick-freezing space is 42.4L / min, and the air volume of the moisturizing space is 11.7L / min. The streamlines of the moisturizing box 10 are uneven, and the air volume cannot fully cover the entire area inside the box, posing a risk of frost. The flow field of the moisture-permeable cover is also uneven.

[0246] Solution 6: The air volume of the quick-freezing space is 42.4L / min, and the air volume of the moisturizing space is 16.6L / min. The streamlines of the moisturizing box 10 are uneven, and the air volume cannot fully cover the entire area inside the box, posing a risk of frost. The flow field of the moisture-permeable cover is extremely uneven.

[0247]

[0248] Measured data shows that the temperature of the quick-freezing space is closely related to the air volume delivered to the space. The greater the air volume, the lower the measured temperature, and the more it meets the requirements for the quick-freezing space. When the air volume in the quick-freezing space is small, the measured temperature is obviously lower than when the air volume is large. When the air volume in the moisturizing space (i.e., air circulation volume / humidor volume) is less than 1, the moisture in the moisturizing box cannot be discharged in time. Due to the effect of the moisture-permeable membrane, the humidity remains below 90%, but frost has already appeared on the inner wall of the moisturizing box and under the moisturizing cover. When the air volume in the moisturizing space (i.e., air circulation volume / humidor volume) is greater than 1, the moisture in the moisturizing box can be effectively discharged, and the effect of the moisture-permeable membrane is also enhanced. At this time, no frost appears on the moisturizing box wall.

[0249] Therefore, the ratio of the air volume of the quick-freezing space to the air volume of the moisturizing space should be between 10 and 20.

[0250] The disclosed embodiment further provides a storage basket, comprising a moisturizing box 10 and an expansion box 40 .

[0251] The moisturizing box 10 is open at the top and is constructed with a first ventilation part 101; the expansion box 40 is a semi-open structure and is constructed with a fourth ventilation part 401; wherein, when the expansion box 40 is semi-enclosed outside the moisturizing box 10, the first ventilation part 101 and the fourth ventilation part 401 are correspondingly arranged and connected, and the ventilation areas of the first ventilation part 101 and the fourth ventilation part 401 partially or completely overlap.

[0252] With the storage basket provided in the embodiment of the present disclosure, the expansion box 40 can be moved laterally relative to the moisturizing box 10. When the expansion box 40 is half-enclosed outside the moisturizing box 10, the ventilation areas of the first ventilation part 101 and the fourth ventilation part 401 partially or completely overlap, so that the air flow rate flowing in and out of the first ventilation part 101 can be variable, thereby enabling the moisturizing box 10 to form different storage conditions, thereby increasing the diversity of storage in the storage basket, especially the moisturizing box 10, meeting the different needs of users and improving user experience.

[0253] For example, when the expansion box 40 is partially enclosed outside the moisturizing box 10 and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 completely overlap, the first storage condition is achieved. When the expansion box 40 is partially enclosed outside the moisturizing box 10 and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially overlap, the air volume of the first ventilation section 101 is reduced, achieving the second storage condition. When the expansion box 40 is pulled horizontally relative to the moisturizing box 10 and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 completely overlap, the third storage condition is achieved. In this case, the air volume flowing into the moisturizing box 10 is maximum. When the expansion box 40 is pulled horizontally relative to the moisturizing box 10 and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially overlap, the fourth storage condition is achieved. The air volume entering the moisturizing box 10 under the fourth storage condition is greater than that under the second storage condition.

[0254] Optionally, the first ventilation portion 101 is disposed around the circumferential side wall of the moisturizing box 10, and the fourth ventilation portion 401 is disposed around the circumferential side wall of the expansion box 40. This helps to ensure the consistency of the fourth ventilation portion 401 and the first ventilation portion 101, thereby ensuring the air intake of the moisturizing box 10.

[0255] Alternatively, when the ventilation area of ​​the fourth ventilation portion 401 partially overlaps with the ventilation area of ​​the first ventilation portion 101, the ventilation area of ​​the fourth ventilation holes 4011 of the fourth ventilation portion 401 may be smaller than the ventilation area of ​​the first ventilation holes 1011 of the first ventilation portion 101. Alternatively, the number of the fourth ventilation holes 4011 of the fourth ventilation portion 401 may be smaller than the number of the first ventilation holes 1011 of the first ventilation portion 101.

[0256] The embodiment of the present disclosure further provides a storage basket, including a moisturizing box 10 and an expansion box 40 .

[0257] The moisturizing box 10 is provided with a moisture-permeable cover, and the side wall is constructed with a third ventilation part 102 located below the moisture-permeable cover; the expansion box 40 can be installed on the outside of the moisturizing box 10, and the side wall is constructed with a fifth ventilation part 402; wherein, the ventilation area of ​​the third ventilation part 102 is partially or completely corresponding to the ventilation area of ​​the fifth ventilation part 402.

[0258] The storage basket provided in the embodiment of the present disclosure can achieve the purpose of controlling moisture and keeping food fresh by using the moisturizing box 10 and the moisture-permeable cover. In addition, the expansion box 40 can not only expand the storage space, but also connect the ventilation area of ​​the fifth ventilation part 402 with the third ventilation part 102, thereby further realizing the humidity adjustment function in the moisturizing box 10 and meeting diverse storage needs.

[0259] Optionally, when the moisturizing box 10 and the expansion box 40 are stacked in a forward direction, the ventilation area of ​​the third ventilation part 102 corresponds to the ventilation area of ​​the fifth ventilation part 402. That is, it can be understood that the ventilation area of ​​the third ventilation part 102 is the same as the ventilation area of ​​the fifth ventilation part 402 and is fully connected.

[0260] Optionally, when the humidifying box 10 and the expansion box 40 are stacked in reverse, the ventilation area of ​​the third ventilation portion 102 is partially corresponding to the ventilation area of ​​the fifth ventilation portion 402. In other words, it can be understood that the ventilation area of ​​the third ventilation portion 102 is partially connected to the ventilation area of ​​the fifth ventilation portion 402, and the third ventilation portion 102 is blocked by the side wall of the expansion box 40, so the actual ventilation area of ​​the third ventilation portion 102 is smaller than the total ventilation area.

[0261] The cool air in the cabinet 50 flows into the moisturizing box 10 through the third ventilation portion 102, preventing the high-humidity air from forming ice or frost on the wall surface of the moisturizing box 10. The ventilation area of ​​the third ventilation portion 102 affects the humidity in the moisturizing box 10. Different ventilation areas will result in different humidity levels in the moisturizing box 10.

[0262] When the expansion box 40 is in use, the humidifying box 10 is separated from the expansion box 40, and the third ventilation portion 102 of the humidifying box 10 is fully ventilated, resulting in a larger ventilation area and lower humidity in the humidifying box 10. When the expansion box 40 is not in use, when stacked with the humidifying box 10 in the forward and reverse directions, the third ventilation portion 102 has different areas, resulting in different humidity levels in the humidifying box 10, thereby allowing the storage of at least two different humidity levels. Therefore, the storage basket provided in this embodiment can maintain at least three different humidity levels, thereby storing three different types of food, meeting the different needs of users.

[0263] Optionally, the opening edge of the cabinet 50 is constructed with a step structure 502 , and the first overlapping portion 104 of the moisturizing box 10 and the third overlapping portion 404 of the expansion box 40 form a hanging ear structure to be overlapped and fixed to the step structure 502 .
