[0002] Refrigeration equipment, such as refrigerators, is a common device used to store food in modern households. Existing refrigeration equipment generally extends the shelf life of food by providing a low-temperature environment.

DETAILED DESCRIPTION

[0029] The following describes this patent in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit this patent, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0030] Reference Figure 1 and Figure 2 The present application provides a refrigeration device 100. The refrigeration device 100 may include an oxygen-regulating storage container and an electrolytic oxygen-regulating module 2. The oxygen-regulating module 2 may include an electrolyte storage chamber, a first electrode, and a second electrode, wherein the first electrode and the second electrode are at least partially exposed to the electrolyte storage chamber. The oxygen-regulating module 2 is configured to form an oxygen-rich atmosphere or an oxygen-depleted atmosphere at the first electrode through an electrochemical reaction. The oxygen-regulating module 2 is disposed inside the oxygen-regulating container 1 to supply the oxygen-rich atmosphere or the oxygen-depleted atmosphere to the oxygen-regulating container 1.

[0031] Placing the oxygen regulating module 2 in the oxygen regulating container 1 can more quickly and directly adjust the oxygen concentration in the container, allowing the oxygen-rich or oxygen-depleted atmosphere to be quickly distributed to every corner of the oxygen regulating container 1, thereby increasing the speed of adjusting the oxygen content in the oxygen regulating container 1 and meeting storage needs more quickly. The built-in oxygen regulating module 2 makes the overall structure of the equipment more compact and integrated, reduces the complexity of external connections and pipelines, and reduces the cost of installation and maintenance. At the same time, it also avoids the risk of leakage or failure caused by external pipeline failures, thereby improving the stability and safety of equipment operation. Placing the oxygen regulating module 2 in the oxygen regulating container 1 can improve the efficiency and accuracy of oxygen regulation, optimize space utilization, simplify equipment design, and enhance stability and safety.

[0032] Reference Figure 2 In one embodiment of the present application, the oxygen regulating container 1 may include a first oxygen regulating container 11 and a second oxygen regulating container 12. The oxygen regulating module 2 is further configured to form an oxygen-rich atmosphere or an oxygen-depleted atmosphere at the second electrode, which is opposite to that at the first electrode, through an electrochemical reaction. The oxygen regulating module 2 is disposed inside the first oxygen regulating container 11 so that the oxygen-rich atmosphere or the oxygen-depleted atmosphere at the first electrode is supplied to the first oxygen regulating container 11. An oxygen regulating circuit 23 is provided between the oxygen regulating module 2 and the second oxygen regulating container 12. The oxygen regulating module 2 supplies the oxygen-rich atmosphere or the oxygen-depleted atmosphere at the first electrode or the second electrode to the interior of the second oxygen regulating container 12 through the oxygen regulating circuit 23.

[0033] When the oxygen regulating module 2 supplies the oxygen-rich atmosphere or the oxygen-depleted atmosphere at the first electrode to the interior of the second oxygen regulating container 12 through the oxygen regulating circuit 23, the same or similar oxygen atmosphere can be formed inside the first oxygen regulating container 11 and the second oxygen regulating container 12, that is, the first oxygen regulating container 11 and the second oxygen regulating container 12 can both be oxygen-rich atmospheres or oxygen-depleted atmospheres, and the oxygen concentrations of the first oxygen regulating container 11 and the second oxygen regulating container 12 can be the same or different.

[0034] By forming the same type of atmosphere (oxygen-rich or oxygen-poor) in the first oxygen regulating container 11 and the second oxygen regulating container 12, the oxygen regulating space of the oxygen regulating module 2 is expanded, while allowing differentiation of oxygen concentration. This design can better cope with the sensitivity of different items to oxygen concentration during storage, forming a storage environment with different oxygen concentrations to effectively extend the shelf life of different foods or items, reduce the occurrence of oxidation or other adverse reactions, provide flexibility and efficiency for the simultaneous storage of items with different needs, and optimize the management and regulation of the storage environment.

[0035] When the oxygen regulating module 2 supplies the oxygen-rich atmosphere or the oxygen-depleted atmosphere at the second electrode to the interior of the second oxygen regulating container 12 through the oxygen regulating circuit 23, opposite oxygen atmospheres are formed in the first oxygen regulating container 11 and the second oxygen regulating container 12, that is, if an oxygen-depleted atmosphere is formed in the first oxygen regulating container 11, an oxygen-rich atmosphere is formed in the second oxygen regulating container 12; if an oxygen-rich atmosphere is formed in the first oxygen regulating container 11, an oxygen-depleted atmosphere is formed in the second oxygen regulating container 12.

[0036] Since the process of the oxygen regulating module 2 generating oxygen-rich and oxygen-poor atmospheres through electrochemical reactions is usually carried out simultaneously, the opposite atmosphere regulation of the two containers is achieved through one oxygen regulating module 2, which saves the need for multiple regulating devices, reduces energy consumption and equipment complexity, and is more environmentally friendly, has lower energy consumption, and the overall equipment is more efficient. This opposite and complementary atmosphere regulation method enables the first oxygen regulating container 11 and the second oxygen regulating container 12 to respectively store items that require completely different oxygen concentration environments. For example, one oxygen regulating container 1 is used to store food that requires a low oxygen atmosphere, while the other container is used to store food that requires a high oxygen atmosphere. In this way, users can meet the oxygen concentration requirements of different items in one device at the same time, improving the applicability and functional diversity of the device.

[0037] Reference Figure 2 and Figure 3In one embodiment of the present application, the oxygen regulation module 2 may include a shell 21. The first electrode, the second electrode, and the electrolyte holding chamber may all be arranged in the shell 21. The oxygen regulation module 2 includes at least one anode conductive plate and at least one cathode conductive plate. The first electrode and the second electrode may be composed of a cathode conductive plate and an anode conductive plate, respectively. Electrolyte may be stored in the electrolyte holding chamber. The anode conductive plate and the cathode conductive plate may be respectively arranged in the electrolyte holding chamber, and each may be at least partially immersed in the electrolyte. The anode conductive plate and the cathode conductive plate may be arranged in an intermittent manner. A waterproof and breathable composite layer may be provided on one or both sides of the cathode conductive plate. The cathode conductive plate and the composite layer together constitute an independent oxygen-generating membrane, so that oxygen in the air can pass through the composite layer into the electrolyte holding chamber, and the electrolyte cannot pass through the composite layer to leak out of the electrolyte holding chamber. The cathode conductive plate can adsorb oxygen in the gas. The power terminal on the anode conductive plate can be led out of the shell 21 and electrically connected to the anode of the power supply. The cathode conductive plate is electrically connected to the cathode of the power supply.

[0038] The housing 21 may be provided with a gas passage connecting the electrolyte chamber and the exterior of the housing 21. During operation, oxygen in the air entering the housing 21 from the exterior of the housing 21 through the gas passage passes through the composite layer and reaches the surface of the cathode conductive plate with the negative electrode. Under the action of the DC electric field, a dissolved oxygen reaction occurs on the surface of the cathode conductive plate, adsorbing oxygen, forming an oxygen-depleted atmosphere at the cathode conductive plate. Subsequently, a reverse reaction occurs on the anode conductive plate, producing oxygen, forming an oxygen-rich atmosphere at the anode conductive plate. The oxygen-rich atmosphere or oxygen-depleted atmosphere formed by the electrochemical reaction can be transported into the oxygen regulating container 1 to form an oxygen-rich atmosphere or an oxygen-depleted atmosphere within the oxygen regulating container 1.

[0039] Reference Figures 2 to 4 In one embodiment of the present application, the housing 21 may be formed with a ventilation opening 22 that communicates with the interior of the first oxygen regulating container 11. The oxygen-rich or oxygen-depleted atmosphere at the first electrode is supplied to the interior of the first oxygen regulating container 11 through the ventilation opening 22. The oxygen regulating circuit 23 includes an interface 231 provided on the housing 21 and a gas port 232 provided on the second oxygen regulating container 12. The oxygen-rich or oxygen-depleted atmosphere at the second electrode is supplied to the interior of the second oxygen regulating container 12 through the interface 231 and the gas port 232.

[0040] Through the flexible design of the atmosphere supply path, the oxygen regulating module 2 can generate opposite oxygen atmospheres at different electrodes and transmit them to the two containers respectively through the air path. This configuration can meet the specific requirements of different items for the atmosphere and broaden the application range of the equipment. Through the ventilation opening 22 set on the shell 21, the oxygen-rich or oxygen-poor atmosphere generated by the first electrode can directly enter the first oxygen regulating container 11. At the same time, the oxygen regulating path 23 passes the oxygen-rich or oxygen-poor atmosphere at the second electrode to the second oxygen regulating container 12 through the interface 231 on the shell 21 and the air port 232 on the second oxygen regulating container 12. This design ensures the smoothness of the atmosphere transmission path, contributes to the efficient transmission and uniform distribution of the atmosphere, and also ensures the independence of the atmosphere between the first oxygen regulating container 11 and the second oxygen regulating container 12, keeps the transmission path clear and independent, avoids cross-interference of the atmosphere, and ensures the stability of the atmosphere inside the two containers.

[0041] Reference Figure 5 or Figure 6 In one embodiment of the present application, the oxygen conditioning module 2 is disposed within the first oxygen conditioning container 11. Air from the first oxygen conditioning container 11 enters the housing 21 through the ventilation opening 22 and undergoes an electrochemical reaction at the first electrode, thereby forming an oxygen-depleted atmosphere there. Simultaneously, an electrochemical reaction occurs at the second electrode, thereby forming an oxygen-rich atmosphere there.

[0042] The ventilation opening 22 may include multiple openings or a single, larger opening. Air within the first oxygen regulating container 11 can enter the first electrode within the housing 21 through a portion of the ventilation opening 22. The electrochemical reaction occurring at the first electrode absorbs oxygen from the air, reducing the oxygen content in the air and thereby forming an oxygen-depleted atmosphere at the first electrode. The oxygen-depleted atmosphere can then flow back into the first oxygen regulating container 11 through the remaining openings of the ventilation opening 22. This cycle gradually reduces the oxygen content within the first oxygen regulating container 11, thereby forming an oxygen-depleted atmosphere within the first oxygen regulating container 11.

[0043] While an electrochemical reaction occurs at the first electrode, creating an oxygen-depleted atmosphere there, an electrochemical reaction also occurs at the second electrode, creating an oxygen-rich atmosphere there. The oxygen-rich atmosphere formed at the second electrode can be pure oxygen, equivalent to adsorbing dissolved oxygen through an electrochemical reaction at the first electrode and then releasing it through an electrochemical reaction at the second electrode. The oxygen-rich atmosphere at the second electrode is transported via oxygen control line 23 to the second oxygen control vessel 12, thereby forming an oxygen-rich atmosphere within the second oxygen control vessel 12.

[0044] In this way, the airflow circulation between the first oxygen regulating container 11 and the oxygen regulating module 2 can be used to reduce the oxygen content in the first oxygen regulating container 11, and at the same time, the oxygen adsorbed from the first oxygen regulating container 11 can be used to increase the oxygen content in the second oxygen regulating container 12. Setting the oxygen regulating module 2 in the first oxygen regulating container 11 can facilitate gas circulation between the oxygen regulating module 2 and the first oxygen regulating container 11, thereby simplifying the gas circulation structure between the oxygen regulating module 2 and the first oxygen regulating container 11. In addition, it is only necessary to set up a path between the oxygen regulating module 2 and the second oxygen regulating container 12 to supply oxygen from the oxygen regulating module 2 to the second oxygen regulating container 12. There is no need to set up a loop between the oxygen regulating module 2 and the second oxygen regulating container 12. This can simplify the oxygen regulating path 23 between the second oxygen regulating container 12 and the oxygen regulating module 2, making the overall structure more compact.

[0045] Reference Figure 7 or Figure 8 or Figure 9 In another embodiment of the present application, the oxygen regulating circuit 23 may include an outlet gas circuit 233 and a return gas circuit 234. The outlet gas circuit 233 includes an outlet port 2321 provided on the wall of the second oxygen regulating container 12 or provided inside the second oxygen regulating container, and a first interface 2311 provided on the housing 21. The return gas circuit 234 includes an air return port 2322 provided on the wall of the second oxygen regulating container 12 or provided inside the second oxygen regulating container 12, and a second interface 2312 provided on the housing 21. The air in the second oxygen regulating container 12 enters the housing 21 through the outlet port 2321 and the first interface 2311, and an electrochemical reaction occurs at the second electrode, forming an oxygen-depleted atmosphere at the second electrode. At the same time, an electrochemical reaction occurs at the first electrode, forming an oxygen-rich atmosphere at the first electrode. The oxygen-depleted atmosphere at the second electrode is supplied to the interior of the second oxygen regulating container 12 through the second interface 2312 and the air return port 2322.

[0046] Through the outlet gas path 233 and the return gas path 234, a gas circulation path can be formed between the second oxygen regulating container 12 and the oxygen regulating module 2, so that the oxygen regulating module 2 can absorb oxygen from the air in the second oxygen regulating container 12, thereby reducing the oxygen content in the second oxygen regulating container 12, and forming an oxygen-depleted atmosphere in the second oxygen regulating container 12. In addition, the oxygen regulating module 2 can transport the generated oxygen to the first oxygen regulating container 11 through the ventilation opening 22, thereby increasing the oxygen content in the first oxygen regulating container 11, and forming an oxygen-rich atmosphere inside the first oxygen regulating container 11.

[0047] Reference Figure 5 、 Figure 7 、 Figure 8In one embodiment of the present application, the first oxygen-conditioning container 11 is disposed within the second oxygen-conditioning container 12, or the second oxygen-conditioning container 12 is disposed within the first oxygen-conditioning container 11. By nesting the two containers, the overall volume of the device can be effectively reduced. The nested structural design enables the oxygen-conditioning module 2 to more efficiently distribute the atmosphere between the two containers. Since the two containers are tightly connected, the atmosphere transmission path is shortened, which makes the generation and supply of oxygen-rich or oxygen-depleted atmosphere faster and more efficient, while reducing the complexity of the gas path.

[0048] Reference Figure 6 、 Figure 9 In another embodiment of the present application, the first oxygen regulating container 11 and the second oxygen regulating container 12 can be arranged in parallel, either vertically or horizontally.

[0049] Reference Figure 10 In one embodiment of the present application, the oxygen conditioning container 1 includes a first oxygen conditioning container 11 and a second oxygen conditioning container 12. The oxygen conditioning module 2 is disposed within the first oxygen conditioning container 11 so that the oxygen-rich atmosphere or the oxygen-depleted atmosphere at the first electrode is supplied to the first oxygen conditioning container 11. A gas flow path 24 is disposed between the first oxygen conditioning container 11 and the second oxygen conditioning container 12. The oxygen-rich atmosphere or the oxygen-depleted atmosphere within the first oxygen conditioning container 11 is supplied to the interior of the second oxygen conditioning container 12 via the gas flow path 24.

[0050] By setting up a gas flow path 24, gas exchange between the first oxygen regulating container 11 and the second oxygen regulating container 12 is achieved, thereby adjusting the oxygen content of the second oxygen regulating container 12. This design is different from the above-mentioned method of using a single oxygen regulating module 2 to separately adjust the oxygen content of the two containers. Since only one oxygen regulating module 2 is required to operate, the oxygen-rich or oxygen-poor atmosphere in the first oxygen regulating container 11 is shared through the gas flow path 24, and the oxygen concentration of the second oxygen regulating container 12 can be efficiently adjusted, avoiding the extra energy consumption caused by adjusting the atmosphere separately for each container. Through the gas flow path 24 between the first oxygen regulating container 11 and the second oxygen regulating container 12, whether it is an oxygen-rich atmosphere or an oxygen-poor atmosphere, it can be quickly transmitted to the second oxygen regulating container 12 through the gas flow path 24, so that the two containers can quickly reach the required oxygen concentration, thereby improving the response speed of the atmosphere adjustment and meeting diverse storage needs.

[0051] Reference Figure 11In one embodiment of the present application, the refrigeration device 100 includes a storage space located outside the oxygen regulating container 1. The refrigeration device 100 also includes a gas transmission line 25 that connects the internal space of the shell 21 with the storage space or the external space of the refrigeration device 100. The air in the storage space or the air outside the refrigeration device 100 enters the shell 21 through the gas transmission line 25 and undergoes an electrochemical reaction at the second electrode to form an oxygen-depleted atmosphere at the second electrode. At the same time, an electrochemical reaction occurs at the first electrode to form an oxygen-rich atmosphere at the first electrode. The shell 21 is formed with a ventilation opening 22 that is connected to the interior of the oxygen regulating container 1. The oxygen-rich atmosphere at the first electrode is supplied to the interior of the oxygen regulating container 1 through the ventilation opening 22.

[0052] Unlike the previous method of generating an oxygen-rich atmosphere by having the oxygen conditioning module 2 absorb oxygen from the air inside the oxygen conditioning container 1, this embodiment introduces air from the storage space of the refrigeration equipment 100 or external air into the housing 21 via the gas line 25. An electrochemical reaction occurs at the second electrode to generate an oxygen-depleted atmosphere, while simultaneously generating an oxygen-rich atmosphere at the first electrode. This oxygen-rich atmosphere is then delivered to the interior of the oxygen conditioning container 1 through the ventilation opening 22. Compared to a closed system, this design utilizes air resources outside the oxygen conditioning container 1, enhancing the flexibility of atmosphere generation.

[0053] Reference Figure 1 and Figure 12 In one embodiment of the present application, a refrigeration device 100 includes a housing 3, a storage compartment 4 formed within the housing 3, and a door 5 for opening and closing the storage compartment 4. An oxygen conditioning container 1 is disposed within the storage compartment 4. The oxygen conditioning container 1 includes a housing 13 and a drawer 14. The housing 13 has a front opening 131. The drawer 14 is retractably mounted within the housing 13 through the front opening 131. The front panel of the drawer 14 is used to open and close the front opening 131 of the housing 13.

[0054] The oxygen regulating container 1 adopts a structural design of a cylinder 13 and a drawer 14. The drawer 14 can be pulled out through the opening in the front of the cylinder 13. Users can conveniently take out or put in stored items from the storage compartment 4 without having to completely open the entire container. This design not only simplifies the process of taking and putting items, but also reduces the chance of gas loss when the container is opened, maintaining a stable environment inside the oxygen regulating container 1. Since the oxygen regulating container 1 adopts a drawer 14 design, users can easily pull out the drawer 14 for cleaning and maintenance. Compared with traditional fixed containers, the drawer 14 design not only improves the flexibility of operation, but also facilitates the timely removal of possible residual dirt and impurities, ensuring that the equipment is always in good operating condition. In addition, the cylinder seal 15 can also be easily replaced and inspected, extending the service life of the equipment.

[0055] Reference Figure 12In an embodiment of the present application, a cylinder sealing element 15 is arranged between the front plate of the drawer 14 and the front wall of the cylinder 13. The cylinder sealing element 15 is used to seal the gap between the front plate of the drawer 14 and the front wall of the cylinder 13.

[0056] The front plate of the drawer 14 and the front wall of the cylinder 13 are sealed by the cylinder sealing element 15, which effectively fills the gap between the front plate of the drawer 14 and the front wall of the cylinder 13, preventing gas leakage. The sealing property is crucial for the oxygen regulating container 1 to maintain a low-oxygen environment inside. By arranging the cylinder sealing element 15, it can be ensured that oxygen does not penetrate from the gap, avoiding the impact on the oxygen concentration inside the container. This design greatly improves the oxygen regulating effect, allowing the stored items to be in a stable low-oxygen environment for a long time, extending the preservation time. When the drawer 14 is closed, the cylinder sealing element 15 between the front plate and the front wall of the cylinder 13 can ensure that the gas is completely enclosed inside the container, effectively preventing the penetration of external oxygen. By maintaining the stability of the internal gas environment, the oxygen regulating container 1 can work in an efficient state continuously, reducing the need for frequent adjustment of oxygen concentration, thereby improving the overall energy efficiency of the equipment.

[0057] In an embodiment of the present application, the storage compartment 4 is a refrigeration compartment. The oxygen regulating container 1 is located in the refrigeration compartment, allowing the oxygen regulating module 2 to work cooperatively with the refrigeration system to effectively control the temperature and gas environment inside the oxygen regulating container 1. Through reasonable layout of the air exchange port 232 and gas flow design, more accurate oxygen concentration regulation can be achieved in a low-temperature environment, extending the preservation period of the stored items, especially for oxygen-sensitive food materials such as fruits, vegetables, and meat.

[0058] Referring to Figure 2 and Figure 12 In an embodiment of the present application, the oxygen regulating module 2 is installed on the left side or right side of the drawer 14. The oxygen regulating module 2 is installed on the left side or right side of the drawer 14, optimizing the internal space layout of the cylinder 13 and avoiding the oxygen regulating module 2 occupying too much storage space inside the cylinder 13. The position arrangement of the oxygen regulating module 2 makes it more convenient to maintain and replace, and also allows the atmosphere regulating system to operate efficiently.

[0059] In the present application, the up-down direction refers to the height direction of the refrigeration equipment 100, the front-rear direction refers to the depth direction of the refrigeration equipment 100, and the left-right direction refers to the width direction of the refrigeration equipment 100, wherein the storage compartment opening faces forward.
