At this time, the humidity cannot be adjusted, which seriously affects the fresh-keeping storage effect of the refrigerator and the user experience. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to 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 the 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, making it impossible for the moisture permeable membrane to perform moisture permeation work after working for a certain period of time. At this time, the humidity cannot be adjusted, which seriously affects the fresh-keeping storage effect of the refrigerator and the user experience.

[0033] To this end, the present 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 with the fresh-keeping compartment 12 through the moisture permeable structure 3; a refrigeration air supply port 13 is arranged on the refrigeration compartment 11, and a return air port 14 is arranged on the fresh-keeping compartment 12, and 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 with the return air port 14 through the first distance 15. A first distance 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 distance 15, and this part of the airflow is used to 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 dynamic and stable internal and external humidity difference environment, maintain the moisture permeability effect of the moisture permeable structure 3, and then ensure the fresh-keeping effect of the refrigeration equipment, thereby 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, so as to achieve the refrigeration effect on the refrigeration compartment 11. Since the return air port 14 is arranged on the fresh-keeping compartment 12, the gas entering the refrigeration compartment 11 can only flow into the fresh-keeping compartment 12 and flow back to the refrigeration duct through the return air port 14 to achieve gas circulation. Since there is a first spacing 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 spacing 15. At the same time, the moisture permeable structure 3 can gather the moisture in the drawer 2 to the side of the first spacing 15. The gas flowing from the first spacing 15 can take away the moisture gathered on the moisture permeable structure 3, destroy the humidity gathering on the surface of the moisture permeable structure 3, establish a dynamically stable internal and external humidity difference environment, maintain the moisture permeability effect of the moisture permeable structure 3, and then ensure the fresh-keeping effect of the refrigeration device and improve the user experience.

[0035] The refrigeration device further comprises an air duct plate 4, which is arranged in the housing 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, and the air duct plate 4 divides the interior of the housing 1 into a refrigeration chamber and a storage chamber, and the refrigerated compartment 11 and the fresh-keeping compartment 12 are formed in the storage chamber, and 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 and the return air port 14. The air vents 13 and the return air vents 14 are both arranged on the air duct plate 4, so as to realize the exchange of gas in the refrigeration cavity and 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 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, and improving the user experience.

[0036] The refrigeration device further comprises a partition plate 5, which is arranged on the air duct plate 4, and the first side surface of the partition plate 5 constitutes the side wall surface of the refrigeration compartment 11, and the second side surface of the partition plate 5 constitutes the side wall surface of the fresh-keeping compartment 12, the first spacing 15 is formed between the drawer 2 and the partition plate 5, and the moisture permeable structure 3 is arranged on the side wall of the drawer 2 facing the partition plate 5. The storage cavity is separated by the partition plate 5 to form the refrigeration compartment 11 and the fresh-keeping compartment 12, so as to realize the separation of the space inside the refrigeration device, and at the same time, the first spacing 15 formed between the partition plate 5 and the drawer 2 is used, and this first spacing 15 can facilitate the pulling and pulling of the drawer 2, and at the same time, the drawer 2 is arranged in close contact with the other side walls of the fresh-keeping compartment 12, so as to limit the airflow to flow only 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 device, and improving the user experience.

[0037] The housing 1 is provided with an opening, through which the user can store items in the refrigerated compartment 11 and operate the drawer 2. A second spacing 16 is provided between the partition plate 5 and the opening, and the refrigerated air supply port 13 is connected with the return air port 14 through the second spacing 16 and the first spacing 15 in sequence. The second spacing 16 is used to ensure the connection between the refrigerated compartment 11 and the fresh-keeping compartment 12. The refrigerated air supply port 13 is located at the back of the refrigerated compartment 11. At this time, the airflow enters the refrigerated compartment 11 from the back of the refrigerated compartment 11 and flows toward the opening, and then flows into the fresh-keeping compartment 12 through the second spacing 16. Since the return air port 14 is located at the back of the fresh-keeping compartment 12, the airflow also needs to flow toward the back of the fresh-keeping compartment 12. Under the restriction of the drawer 2 and the partition plate 5, the airflow can only flow through the first spacing 15, further restricting the airflow from flowing through the moisture permeable structure 3, thereby ensuring the moisture permeability effect of the moisture permeable structure 3 and the fresh-keeping effect of the refrigeration equipment, and improving the user experience.

[0038] The refrigeration device further includes a drawer cover, which is buckled on the drawer 2, the partition plate 5 is located above the drawer 2, and the distance is formed between the drawer cover and the partition plate 5, and the moisture permeable structure 3 is arranged on the drawer cover. The drawer cover and the drawer 2 are buckled to ensure the relative sealing of the inner space of the drawer 2, and the gas and cold between the drawer 2 and the fresh-keeping chamber 12 can only be transferred through the moisture permeable structure 3, so that the 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, and the fresh-keeping effect of the drawer 2 is ensured.

[0039] Furthermore, a variable temperature chamber 17 is formed in the housing 1, and the variable temperature chamber 17 is relatively sealed with the refrigerating chamber 11 and the fresh-keeping chamber 12, and the circulating air volume in the variable temperature chamber 17 is adjustable. The cold air volume generated by the refrigerating equipment is certain, and the air volume of the refrigerating chamber 11 can be adjusted by adjusting the air volume in the variable temperature chamber 17, thereby adjusting the air volume at the first spacing 15, so as to adjust the humidity adjustment efficiency of the moisture permeable structure 3, thereby achieving the purpose of controllably adjusting the humidity inside the drawer 2.

[0040] Specifically, a refrigeration duct is formed in the shell 1, and the refrigeration duct can be surrounded by the duct plate 4 and the shell 1. The variable temperature chamber 17 is provided with a variable temperature air supply port 18, and the refrigeration air supply port 13 and the variable temperature air supply port 18 are both connected to the refrigeration duct. The variable temperature chamber 17 and the refrigeration chamber 11 simultaneously obtain cold air from the refrigeration 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 chamber 17, and then the gas flow passing through the first spacing 15 can be adjusted to adjust the ability to take away water vapor from the moisture permeable structure 3, so as to adjust the humidity adjustment efficiency of the moisture permeable structure 3, thereby achieving the purpose of controllable adjustment of the humidity inside the drawer 2. For example, when the circulating air volume of the variable temperature chamber 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 chamber 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 finally 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 adjusting mechanism 6, which is arranged at the variable temperature air supply port 18, and the adjusting mechanism 6 can adjust the flow area of ​​the variable temperature air supply port 18. The variable temperature air supply port 18 is shielded by the adjusting mechanism 6. 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, so as to realize the linkage control of the variable temperature regulation and humidity regulation of the refrigeration equipment, and ensure 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, the air volume and transportation volume simulation analysis of the refrigeration equipment can be performed after setting the first spacing 15, and the humidity curve 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 regulation and humidity regulation 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 refrigeration compartment 11. A baffle is arranged 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 arranged 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.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
