[0002] As people's demands for higher quality of life and living standards continue to rise, the demand for diversified and personalized food storage at home is also growing. In the current refrigerator market, most refrigerator compartment designs still rely on traditional fruit and vegetable boxes without special preservation functions. Although these boxes are sometimes labeled "fresh storage," they actually do not provide special preservation functions, thus failing to meet consumers' growing demand for long-term freshness of fruits and vegetables.

[0003] Although there is a technical solution in the prior art for regulating humidity by using a moisture-permeable membrane, the moisture-permeable membrane can permeate moisture from the inside to the outside and stably maintain humidity under high humidity. However, during the moisture permeation process, water molecules continue to accumulate on the outside of the membrane, resulting in a decrease in the humidity difference between the inside and the outside, and the moisture permeation effect also continues to decrease. As a result, the moisture-permeable membrane cannot perform moisture permeation after working for a certain period of time, and the humidity cannot be adjusted at this time, which seriously affects the fresh-keeping storage effect of the refrigerator and the user experience.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] Although there is a technical solution in the prior art for regulating humidity by using a moisture-permeable membrane, the moisture-permeable membrane can permeate moisture from the inside to the outside and stably maintain humidity under high humidity. However, during the moisture permeation process, water molecules continue to accumulate on the outside of the membrane, resulting in a decrease in the humidity difference between the inside and the outside, and the moisture permeation effect also continues to decrease. As a result, the moisture-permeable membrane cannot perform moisture permeation after working for a certain period of time, and the humidity cannot be adjusted at this time, which seriously affects the fresh-keeping storage effect of the refrigerator and the user experience.

[0033] To this end, this application provides a Figures 1 to 5 The refrigeration device shown includes: a shell 1, in which a refrigeration compartment 11 and a fresh-keeping compartment 12 are formed; a drawer 2, which is arranged in the fresh-keeping compartment 12; a moisture-permeable structure 3, which is arranged on the drawer 2, and the interior of the drawer 2 is connected to the fresh-keeping compartment 12 through the moisture-permeable structure 3; a refrigeration air supply port 13 is provided on the refrigeration compartment 11, and a return air port 14 is provided on the fresh-keeping compartment 12. A first distance 15 is provided between the moisture-permeable structure 3 and the inner wall of the fresh-keeping compartment 12, and the refrigeration air supply port 13 is connected to the return air port 14 through the first distance 15. A first gap 15 is formed between the moisture-permeable structure 3 and the fresh-keeping compartment 12, so that the airflow entering the refrigerated compartment 11 can only flow to the return air outlet 14 through the first gap 15. This part of the airflow is used to carry away the moisture accumulated on the moisture-permeable structure 3, thereby destroying the humidity accumulation on the surface of the moisture-permeable structure 3, establishing a dynamic and stable internal and external humidity difference environment, maintaining the moisture permeability of the moisture-permeable structure 3, and thus ensuring the fresh-keeping effect of the refrigeration equipment and improving the user experience.

[0034] When the refrigeration device is working, the cold air in the refrigeration duct in the shell 1 can be sent into the refrigeration compartment 11 through the refrigeration air supply port 13, thereby achieving a cooling effect on the refrigeration compartment 11. Since the return air port 14 is provided on the fresh-keeping compartment 12, the gas entering the refrigeration compartment 11 can only flow into the fresh-keeping compartment 12 and return to the refrigeration duct through the return air port 14, thereby achieving gas circulation. Since there is a first gap 15 between the moisture-permeable structure 3 and the fresh-keeping compartment 12, the gas flowing to the return air port 14 can only flow through the first gap 15. At the same time, the moisture-permeable structure 3 can gather the moisture in the drawer 2 to the side of the first gap 15. The gas flowing from the first gap 15 can take away the moisture accumulated on the moisture-permeable structure 3, destroy the humidity accumulation on the surface of the moisture-permeable structure 3, establish a dynamically stable internal and external humidity difference environment, maintain the moisture permeability of the moisture-permeable structure 3, thereby ensuring the fresh-keeping effect of the refrigeration device and improving the user experience.

[0035] The refrigeration device further comprises an air duct plate 4, which is arranged in the shell 1, and part of the air duct plate 4 constitutes the back plate of the refrigerated compartment 11, and part of the air duct plate 4 constitutes the back plate of the fresh-keeping compartment 12. The refrigerated air supply port 13 and the return air port 14 are both arranged on the air duct plate 4. The air duct plate 4 divides the interior of the shell 1 into a refrigeration chamber and a storage chamber. The refrigerated compartment 11 and the fresh-keeping compartment 12 are formed in the storage chamber. The refrigeration chamber is provided with an evaporator and other structures for refrigeration, thereby forming cold air to refrigerate the refrigerated air supply port 13. The air vents 13 and the return air vents 14 are both arranged on the air duct plate 4 to realize the exchange of gas in the refrigeration cavity and the gas in the storage cavity, thereby achieving refrigeration of the refrigerated compartment 11 and the fresh-keeping compartment 12. At the same time, the refrigerated air supply vents 13 and the return air vents 14 are both arranged on the air duct plate 4, which further limits the flow direction of the gas in the refrigerated compartment 11 and the fresh-keeping compartment 12, ensuring that the gas can only flow through the first spacing 15, thereby ensuring the moisture permeability effect of the moisture permeable structure 3 and the fresh-keeping effect of the refrigeration equipment, thereby improving the user experience.

[0036] The refrigeration device further includes a partition plate 5, which is disposed on the air duct plate 4. A first side surface of the partition plate 5 forms a side wall surface of the refrigerated compartment 11, and a second side surface of the partition plate 5 forms a side wall surface of the fresh-keeping compartment 12. A first gap 15 is formed between the drawer 2 and the partition plate 5, and the moisture-permeable structure 3 is disposed on the side wall of the drawer 2 facing the partition plate 5. The partition plate 5 is used to separate the storage cavity to form the refrigerated compartment 11 and the fresh-keeping compartment 12, thereby achieving a partition within the refrigeration device. The first gap 15 formed between the partition plate 5 and the drawer 2 facilitates the drawing and extension of the drawer 2. Furthermore, the drawer 2 is positioned in close contact with the other side walls of the fresh-keeping compartment 12, thereby restricting airflow to only through the first gap 15. This ensures the moisture permeability of the moisture-permeable structure 3 and the fresh-keeping effect of the refrigeration device, thereby improving the user experience.

[0037] The housing 1 is provided with an opening through which a user can store items in the refrigerated compartment 11 and operate the drawer 2. A second gap 16 is defined between the partition plate 5 and the opening. The refrigerated air supply vent 13 communicates with the return air vent 14 through the second gap 16 and the first gap 15, respectively. The second gap 16 ensures communication between the refrigerated compartment 11 and the fresh food compartment 12. The refrigerated air supply vent 13 is located at the back of the refrigerated compartment 11. Airflow enters the refrigerated compartment 11 from the back and flows toward the opening before flowing into the fresh food compartment 12 through the second gap 16. Since the return air vent 14 is located at the back of the fresh food compartment 12, airflow also needs to flow toward the back of the fresh food compartment 12. Due to the restriction of the drawer 2 and the partition plate 5, airflow can only flow through the first gap 15, further restricting airflow from passing through the moisture-permeable structure 3. This ensures the moisture permeability of the moisture-permeable structure 3 and the fresh food preservation effect of the refrigeration device, thereby improving the user experience.

[0038] The refrigeration device further includes a drawer cover, which is buckled onto the drawer 2. The partition plate 5 is located above the drawer 2, with the gap formed between the drawer cover and the partition plate 5. The moisture-permeable structure 3 is disposed on the drawer cover. The drawer cover and the drawer 2 are buckled together to ensure that the interior space of the drawer 2 is relatively sealed. Gas and cold energy between the drawer 2 and the fresh-keeping compartment 12 can only be transferred through the moisture-permeable structure 3, so that moisture in the drawer 2 can only be discharged through the moisture-permeable structure 3, so that the humidity inside the drawer 2 is maintained within a preset range, thereby ensuring the fresh-keeping effect of the drawer 2.

[0039] Furthermore, a variable temperature compartment 17 is formed within the housing 1. The variable temperature compartment 17 is relatively sealed from both the refrigerated compartment 11 and the fresh food compartment 12, and the circulating air volume within the variable temperature compartment 17 is adjustable. The amount of cold air generated by the refrigeration equipment is constant. By adjusting the air volume within the variable temperature compartment 17, the air volume to the refrigerated compartment 11 can be adjusted, thereby adjusting the air volume at the first spacing 15, thereby adjusting the humidity regulation efficiency of the moisture-permeable structure 3, thereby achieving controllable regulation of the humidity within the drawer 2.

[0040] Specifically, a cooling duct is formed within the housing 1. This duct can be enclosed by an air duct plate 4 and the housing 1. A variable temperature air supply port 18 is provided on the variable temperature compartment 17. Both the refrigeration air supply port 13 and the variable temperature air supply port 18 are connected to the cooling duct. The variable temperature compartment 17 and the refrigeration compartment 11 simultaneously draw cold air from the cooling duct. Since the amount of cold air in the refrigeration duct is constant, the air supply volume of the refrigeration air supply port 13 can be adjusted by adjusting the circulating air volume of the variable temperature compartment 17. This, in turn, adjusts the air flow rate passing through the first gap 15 to adjust the ability to remove moisture from the moisture-permeable structure 3, thereby adjusting the humidity regulation efficiency of the moisture-permeable structure 3 and thereby achieving controllable humidity regulation within the drawer 2. For example, when the circulating air volume of the variable temperature compartment 17 is increased, the air volume of the refrigerated air supply port 13 is reduced, the gas flow rate at the first spacing 15 is reduced, the water vapor taken away from the moisture permeable structure 3 is reduced, and the moisture permeability efficiency of the moisture permeable structure 3 to the drawer 2 is reduced; and when the circulating air volume of the variable temperature compartment 17 is reduced, the air volume of the refrigerated air supply port 13 is increased, the gas flow rate at the first spacing 15 is increased, the water vapor taken away from the moisture permeable structure 3 is increased, and the moisture permeability efficiency of the moisture permeable structure 3 to the drawer 2 is increased, and ultimately the humidity of the drawer 2 is kept within a preset range, thereby ensuring the freshness preservation effect of the refrigeration equipment and improving the user experience.

[0041] Among them, the refrigeration equipment also includes an adjustment mechanism 6, which is arranged at the variable temperature air supply port 18, and the adjustment mechanism 6 can adjust the flow area of ​​the variable temperature air supply port 18. The adjustment mechanism 6 is used to block the variable temperature air supply port 18. By adjusting the shielding area of ​​the variable temperature air supply port 18, the purpose of adjusting the flow area of ​​the variable temperature air supply port 18 is achieved, and then the circulating air volume of the variable temperature chamber 17 and the air volume at the first spacing 15 are adjusted, thereby realizing the linkage control of the variable temperature adjustment and humidity adjustment of the refrigeration equipment, ensuring that the refrigeration equipment can achieve the best refrigeration and preservation effect.

[0042] The value range of the first spacing 15 is 10 mm to 25 mm. When designing the value of the first spacing 15, after setting the first spacing 15, the air volume and flow rate simulation analysis of the refrigeration equipment can be performed, and the humidity curves inside the drawer 2 and above the moisture-permeable structure 3 can be simultaneously detected. By testing at different heights, the optimal value of the first spacing 15 can be obtained, which can also ensure that the linkage of variable temperature control and humidity control achieves the optimal effect.

[0043] like Figure 1 As shown, the fresh-keeping compartment 12 and the temperature-changing compartment 17 are arranged side by side along the width direction of the shell 1 and are both located below the refrigerated compartment 11. A baffle is provided between the fresh-keeping compartment 12 and the temperature-changing compartment 17. The edge of the baffle is sealed with the partition plate 5, the air duct plate 4 and the inner wall of the shell 1, thereby ensuring the sealing effect of the temperature-changing compartment 17. At the same time, part of the air duct plate 4 constitutes the back plate of the temperature-changing compartment 17, and the temperature-changing air supply port 18 and the return air port 14 of the temperature-changing compartment 17 are both provided on the air duct plate 4, thereby achieving the cooling effect of the temperature-changing compartment 17. Moreover, since the flow area of ​​the temperature-changing air supply port 18 is adjustable, the temperature regulation of the temperature-changing compartment 17 can be ensured.

[0044] The moisture-permeable structure 3 is a moisture-permeable membrane. The airflow within the first spacing 15 can flow through the surface of the moisture-permeable membrane, thereby taking away the water vapor on the surface of the moisture-permeable membrane, so that the moisture-permeable membrane can continue to gather the moisture in the drawer 2 on the other side, thereby achieving the purpose of regulating the humidity in the drawer 2.

[0045] The refrigeration equipment includes a refrigerator.
