Description

Refrigeration equipment

[0001] This application claims priority to the following two patents: 1. Chinese Patent Application No. 202411595661.3, filed on November 8, 2024; 2. Chinese Patent Application No. 202422732036.0, filed on November 8, 2024. The entire contents of the above two patent applications are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical appliances, specifically to a refrigeration device. Background Technology

[0003] Refrigeration equipment, such as refrigerators, is a common household appliance used for storing food. Existing refrigeration systems generally extend the shelf life of food by providing a low-temperature environment. However, in the storage of fresh produce such as fruits and vegetables, controlling oxygen concentration is also crucial for delaying spoilage and reducing aging. For example, fruits and vegetables effectively reduce respiration in a low-oxygen environment, thus prolonging freshness, while meat products require a relatively high-oxygen environment to inhibit the growth of anaerobic bacteria. Therefore, existing designs have the following drawback: they lack control over oxygen concentration and cannot provide the necessary oxygen environment for the food.

[0004] The inclusion of any related technologies in this specification does not imply confirmation or recommendation that such related technologies constitute part of the general knowledge of any jurisdiction, or that it is reasonably expected that such related technologies will be understood, regarded as related and / or combined with other related technologies by a person skilled in the art.

[0005] Application content

[0006] The purpose of this application is to provide a refrigeration device having an internal oxygen concentration adjustable container to solve the problems in the prior art.

[0007] To achieve the above objectives, this application provides a refrigeration device, comprising:

[0008] container;

[0009] An oxygen control module, which is connected to the container, is used to regulate the oxygen content within the container.

[0010] The refrigeration equipment provided in this application allows the oxygen concentration inside the container to be controlled by an oxygen control module to create a low-oxygen environment or a high-oxygen ring, thereby meeting the preservation and storage needs of different food ingredients.

[0011] Furthermore, the oxygen control module is located outside the container, and the container has low oxygen passages and high oxygen passages that connect the inside and outside of it. The oxygen control module has a low oxygen interface corresponding to the low oxygen passage and a high oxygen interface corresponding to the high oxygen passage.

[0069] The present application will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any modifications to the structure, method, or function made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0070] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0071] Referring to Figures 1 and 2, one embodiment of this application provides a refrigeration device 100. The refrigeration device 100 may include a container 10 and an oxygen control module 20.

[0072] Container 10 is used to store food such as vegetables and fruits. It can be understood as a box-shaped object placed in a compartment of a refrigeration device (such as a cold storage compartment), or a structure that isolates storage space in a compartment, or an inner liner structure that forms an entire compartment.

[0073] Referring to Figures 2-3, the oxygen control module 20 is located outside the container 10. It includes a low-oxygen interface 201 and a high-oxygen interface 202. External air can enter the oxygen control module 20 through the low-oxygen interface 201. After the external air enters the oxygen control module 20, the oxygen control module 20 will discharge the oxygen in the air through the high-oxygen interface 202, and low-oxygen gas will be formed inside the oxygen control module 20.

[0074] In this article, low-oxygen gas is gas with an oxygen content lower than that of the atmosphere, and high-oxygen gas is gas with an oxygen content higher than that of the atmosphere.

[0075] The container 10 has a low-oxygen through-hole 101 and a high-oxygen through-hole 102 connecting its interior and exterior. The low-oxygen interface 201 and the low-oxygen through-hole 101 are correspondingly arranged, and the high-oxygen interface 202 and the high-oxygen through-hole 102 are correspondingly arranged. The refrigeration equipment also includes a converter 30 disposed between the container 10 and the oxygen control module 20. The converter 30 is used to control whether the low-oxygen interface 201 and the low-oxygen through-hole 101 are connected, and whether the high-oxygen interface 202 and the high-oxygen through-hole 102 are connected.

[0076] The converter 30 includes a first state and a second state. In the first state, the low-oxygen interface 201 connects to the low-oxygen through-hole 101, which in turn connects to the interior of the container 10, while the high-oxygen interface 202 connects to the exterior of the container 10. When the oxygen control module 20 is operating, air from inside the container 10 enters it. The oxygen control module 20 then discharges oxygen from this air to the exterior of the container 10 through the high-oxygen interface 202, creating a low-oxygen atmosphere inside the module. Because the oxygen control module 20 and the interior of the container 10 are connected, the oxygen content inside the container 10 decreases due to natural airflow, thus creating a low-oxygen region inside the container 10. In this text, the exterior of the container 10 refers to the atmosphere.

[0077] When the converter 30 is in the second state, the high oxygen interface 202 is connected to the high oxygen through hole 102, which in turn connects to the inside of the container 10, and the low oxygen interface 201 is connected to the outside of the container 10. Atmospheric air can enter the oxygen control module 20 through the low oxygen interface 201. The oxygen control module 20 will discharge the oxygen in the air that enters it through the high oxygen interface 202 and the high oxygen through hole 102 to the inside of the container 10, thereby increasing the oxygen content in the air inside the container 10 and making the inside of the container 10 a high oxygen area.

[0078] Understandably, container 10 is not completely sealed. When oxygen enters container 10 through high oxygen vent 102, the air in container 10 will leak out through the gaps in container 10.

[0079] The oxygen control module 20 includes a first electrode, a second electrode, and an electrolyte filling the space between the first and second electrodes. The oxygen control module 20 comes into contact with air from inside the container 10 through the first electrode. Oxygen from the air inside the container 10 undergoes a reduction reaction at the first electrode: O2 + 2H2O + 4e- - →4OH - Correspondingly, an oxidation reaction occurs at the second electrode, producing oxygen gas, i.e.: 4OH- - →O2 + 2H2O + 4e - The oxygen generated at the second electrode can be released into the atmosphere. Therefore, the oxygen control module 20 can transfer oxygen from container 10 into the atmosphere, thereby reducing the oxygen concentration inside container 10.

[0080] As can be imagined, to increase the oxygen content in container 10, the first electrode can be brought into contact with air from the atmosphere. The oxygen in the air from the atmosphere will undergo a reduction reaction at the first electrode, namely: O2 + 2H2O + 4e - →4OH - Correspondingly, an oxidation reaction occurs at the second electrode, producing oxygen gas, i.e.: 4OH- - →O2 + 2H2O + 4e - The oxygen generated at the second electrode is discharged into container 10, which can increase the oxygen content in container 10.

[0081] In summary, the refrigeration equipment provided in this application allows for the alteration of the oxygen content inside the container 10 by controlling whether the converter 30 is in the first or second state. This enables the container 10 to be configured as a high-oxygen or low-oxygen area according to customer needs. Specifically, when the converter 30 is in the first state, the container 10 becomes a low-oxygen area; when the converter 30 is in the second state, the container 10 becomes a high-oxygen area.

[0082] As shown in Figure 2-11, in the first specific embodiment of this application, the converter 30 includes a valve seat 31 that is movably disposed relative to the container 10 along a first direction. The valve seat 31 includes a main body 311 and a plurality of adapter ports 312 arranged along the first direction on the main body 311.

[0083] It should be noted that in this article, the first direction refers to the up-down direction when the container 10, the oxygen control module 20, and the converter 30 are in the state shown in Figure 9.

[0084] The adapter 312 includes a first adapter 3121 and a second adapter 3122, and the valve seat 31 can move along a first direction to a first position and a second position. When the converter 30 is in the first state, the valve seat 31 is in the first position. When the converter 30 is in the second state, the valve seat 31 is in the second position. That is, when the valve seat 31 switches between the first position and the second position, the converter 30 will also switch between the first state and the second state.

[0085] Specifically, when valve seat 31 is in the first position (as shown in Figures 8-9), the first adapter 3121 connects to the low-oxygen interface 201 and the low-oxygen through hole 101, thereby allowing the oxygen control module 20 to connect to the interior of the container 10. When valve seat 31 is in the second position (as shown in Figures 10-11), the second adapter 3122 connects to the high-oxygen interface 202 and the high-oxygen through hole 102, thereby allowing oxygen discharged from the high-oxygen interface 202 of the oxygen control module 20 to enter the interior of the container 10.

[0086] Furthermore, the adapter 312 also includes a third adapter 3123 and a fourth adapter 3124. When the valve seat 31 is in the first position (as shown in Figures 8-9), one end of the third adapter 3123 is connected to the high-oxygen port 202, and the other end is connected to the outside of the container 10. When the valve seat 31 is in the first position, the oxygen control module 20 needs to discharge the oxygen in its internal air through the high-oxygen port 202. With the above configuration, the oxygen discharged from the high-oxygen port 202 will be discharged to the outside of the container 10 after passing through the third adapter 3123.

[0087] When valve seat 31 is in the second position (as shown in Figure 10-11), one end of the fourth adapter 3124 is connected to the low oxygen port 201, and the other end is connected to the outside of container 10. When valve seat 31 is in the second position, external air needs to enter the oxygen control module 20 so that oxygen can be discharged from the high oxygen port 202 of the oxygen control module 20. With the above setting, external air enters the low oxygen port 201 through the fourth adapter 3124 and then enters the oxygen control module 20.

[0088] In other embodiments, the third adapter 3123 and the fourth adapter 3124 may be omitted. When the valve seat 31 is in the first position, there is a gap between it and the high-oxygen interface 202, and the air outlet of the high-oxygen interface 202 is exposed to the atmosphere, thus directly connecting to the atmosphere. Similarly, when the valve seat 31 is in the second position, there is a gap between it and the low-oxygen interface 201, and the air inlet of the low-oxygen interface 201 is exposed to the atmosphere, thus directly connecting to the atmosphere.

[0089] As shown in Figures 4-5, in this embodiment, the main body 311 includes a first side 3125, a second side 3126, and a third side 3127 located on different sides thereon. The two ends of the first adapter 3121 and the second adapter 3122 respectively penetrate through the first side 3125 and the second side 3126, and the two ends of the third adapter 3123 and the fourth adapter 3124 respectively penetrate through the first side 3125 and the third side 3127.

[0090] The low-oxygen interface 201 and high-oxygen interface 202 on the oxygen control module 20 are located near the first side 3125, and the low-oxygen through hole 101 and high-oxygen through hole 102 on the container 10 are located near the second side 3126. In this embodiment, the first side 3125 and the second side 3126 are two opposite sides on the main body 311, and the third side 3127 connects the first side 3125 and the second side 3126. The container 10 and the oxygen control module 20 are located on opposite sides of the converter 30, respectively. The first adapter 3121 and the second adapter 3122 are cylindrical and extend through the first side 3125 and the second side 3126, and the third adapter 3123 and the fourth adapter 3124 are L-shaped and extend through the first side 3125 and the third side 3127.

[0091] In this embodiment, two low-oxygen interfaces 201 and two low-oxygen through holes 101 are provided, with each low-oxygen interface 201 and each low-oxygen through hole 101 corresponding to the other. Correspondingly, two first adapter interfaces 3121 and two third adapter interfaces 3123 are also provided. When the valve seat 31 is in the first position, the two first adapter interfaces 3121 are respectively connected to the two low-oxygen interfaces 201 and the two low-oxygen through holes 101. In this way, the air in the container 10 and the air in the oxygen control module 20 can circulate. That is, the air in the container 10 can enter the oxygen control module 20 through one first adapter interface 3121, and the low-oxygen gas generated in the oxygen control module 20 can enter the container 10 through the other first adapter interface 3121. When the valve seat 31 is in the second position, the two third adapter interfaces 3123 are respectively connected to the two low-oxygen interfaces 201 and the outside of the container 10. The air outside the container 10 can enter the oxygen control module 20 through the two third adapter interfaces 3123.

[0092] As shown in FIGS. 3, 9, and 10, the converter 30 further includes a fixing plate 32 fixedly arranged relative to the container 10. The valve seat 31 is slidably connected to the fixing plate 32 in a first direction. The fixing plate 32 is provided with a first mark 321 and a second mark 322 arranged in the first direction. When the valve seat 31 is in the first position, it covers the second mark 322 to expose the first mark 321. When the valve seat 31 is in the second position, it covers the first mark 321 to expose the second mark 322.

[0093] The functions of the first mark 321 and the second mark 322 are to show the state inside the container 10. With the above arrangement, when the valve seat 31 moves to the first position and the second position in the first direction, it will correspondingly cover one of the first mark 321 and the second mark 322 and expose the other. Thus, by observing the exposed mark, the user can understand the state inside the container 10.

[0094] As described above, when the valve seat 31 is in the first position, the inside of the container 10 is a low-oxygen area. When the valve seat 31 is in the second position, the inside of the container 10 is a high-oxygen area. Therefore, the first mark 321 represents that the inside of the container 10 is a low-oxygen area, and the second mark 322 represents that the inside of the container 10 is a high-oxygen area.

[0095] In this embodiment, the first mark 321 is specifically the Chinese character "low oxygen", and the second mark 322 is specifically the Chinese character "high oxygen". It can be understood that the first mark 321 and the second mark 322 can also use other symbols, as long as the two are distinguishable. For example, the first mark 321 can be the letter "L", the second mark 322 can be the letter "H", or the first mark 321 can be the number "1", and the second mark 322 can be the number "2".

[0096] As shown in FIGS. 3 and 5, a sliding limiting structure 33 is provided between the valve seat 31 and the fixing plate 32 for limiting the movable range of the valve seat 31 relative to the fixing plate 32 from the first position to the second position.

[0097] In one embodiment, the sliding limiting structure 33 includes a chute 331 opened on the fixing plate 32 and a limiting bar 332 connected to the valve seat 31 and slidably arranged in the chute 331. In the first direction, the size occupied by the chute 311 is larger than the size occupied by the limiting bar 332. When the valve seat 31 moves relative to the fixing plate 32 in the first direction, the limiting bar 332 follows the valve seat 31 to move and slide in the chute 331. When the valve seat 31 moves to the first position and the second position, the limiting bar 332 will move to the end of the chute 331 and abut against the fixing plate 32, so that it cannot move further.

[0098] As shown in Figures 12-19, in the second embodiment of this application, the converter 30 includes a base 34 and a valve core 35 rotatably disposed within the base 34. The base 34 includes a first opening 341 communicating with the low-oxygen interface 201, a second opening 342 communicating with the low-oxygen through hole 101, a third opening 343 communicating with the high-oxygen interface 202, a fourth opening 344 communicating with the high-oxygen through hole 102, a fifth opening 345 communicating with the outside of the container 10, and a sixth opening 346. The valve core 35 can be rotated to a third position and a fourth position. When the converter 30 is in the first state, the valve core 35 is in the third position; when the converter 30 is in the second state, the valve core 35 is in the fourth position. That is, rotating the valve core 35 allows the converter 30 to switch between the first state and the second state, thereby controlling whether the low-oxygen interface 201 and the low-oxygen through hole 101 are connected and whether the high-oxygen interface 202 and the high-oxygen through hole 102 are connected.

[0099] The converter 30 is configured such that when the valve core 35 is in the third position (as shown in Figure 17), the first opening 341 and the second opening 342 are connected, the third opening 343 and the sixth opening 346 are connected, and when the valve core 35 is in the fourth position (as shown in Figure 18), the third opening 343 and the fourth opening 344 are connected, and the first opening 341 and the fifth opening 345 are connected.

[0100] With the above configuration, when the valve core 35 is in the third position, the low-oxygen interface 201 and the low-oxygen through hole 101 are connected, while the high-oxygen interface 202 is connected to the outside of the container 10. Thus, the low-oxygen interface 201 of the oxygen control module 20 can connect to the inside of the container 10, and the air inside the container 10 can enter the oxygen control module 20 through the low-oxygen interface 201. The oxygen in the air entering the oxygen control module 20 can be discharged from the high-oxygen interface 202 to the outside of the container 10 under the action of the oxygen control module 20. In this way, a low-oxygen environment can be formed inside the container 10. When the valve core 35 is in the fourth position, the high-oxygen interface 202 and the high-oxygen through hole 102 are connected, while the low-oxygen interface 201 is connected to the outside of the container 10. The air outside the container 10 can enter the oxygen control module 20 through the low-oxygen interface 201, and the oxygen in the air entering the oxygen control module 20 can be discharged from the high-oxygen interface 202 and enter the inside of the container 10. In this way, a high-oxygen environment can be formed inside the container.

[0101] As shown in Figures 17-18, in this embodiment, the valve core 35 has a first three-way hole 351 and a second three-way hole 352 arranged along its axial direction. The first three-way hole 351 includes a first port 3511, a second port 3512, and a third port 3513 located on the outer peripheral surface of the valve core 35. The second three-way hole 352 includes a fourth port 3521, a fifth port 3522, and a sixth port 3523 located on the outer peripheral surface of the valve core 35. The first port 3511, the second port 3512, and the third port 3513 of the first three-way hole 351 are interconnected, and the fourth port 3521, the fifth port 3522, and the sixth port 3523 of the second three-way hole 352 are interconnected.

[0102] When the valve core 35 is in the third position (as shown in Figure 17), the first port 3511 corresponds to the first opening 341, the second port 3512 corresponds to the second opening 342, the fifth port 3522 corresponds to the sixth opening 346, the sixth port 3523 corresponds to the third opening 343, and the remaining third port 3513 and fourth port 3521 are closed by the inner wall of the seat 34. In this way, the first opening 341 will be connected to the second opening 342, and the third opening 343 will be connected to the sixth opening 346.

[0103] When the valve core 35 is in the fourth position (as shown in Figure 18), the first port 3511 corresponds to the fifth opening 345, the third port 3513 corresponds to the first opening 341, the fourth port 3521 corresponds to the fourth opening 344, the fifth port 3522 corresponds to the third opening 343, and the remaining second port 3512 and sixth port 3523 are closed by the inner wall of the seat 34. In this way, the first opening 341 will be connected to the fifth opening 345, and the third opening 343 will be connected to the fourth opening 344.

[0104] As shown in Figures 15-16, in this embodiment, the base 34 includes a fourth side 347, a fifth side 348, a sixth side 349, and a seventh side 3410 located on its outer side. The fourth side 347 and the sixth side 349 are arranged opposite each other, as are the fifth side 348 and the seventh side 3410. The oxygen control module 20 is located near the fourth side 347, and the container 10 is located near the sixth side 349. The first opening 341 and the third opening 343 are located on the fourth side 347, the second opening 342 and the fourth opening 344 are located on the sixth side 349, the fifth opening 345 is located on the seventh side 3410, and the sixth opening 346 is located on the fifth side 348. The first three-way hole 351 and the second three-way hole 352 are both approximately "T"-shaped. The first port 3511 and the second port 3512 of the first three-way hole 351 are two ports arranged opposite each other, and the fourth port 3521 and the fifth port 3522 of the second three-way hole 352 are two ports arranged opposite each other.

[0105] It is conceivable that the positions of the first opening 341 to the sixth opening 346 and the positions of each port of the first three-way hole 351 and the second three-way hole 352 in this embodiment are not limited to the situation described above, and can be adjusted accordingly as needed. When the valve core 35 is in the third position, the first port 3511 corresponds to the first opening 341, the second port 3512 corresponds to the second opening 342, the fifth port 3522 corresponds to the sixth opening 346, and the sixth port 3523 corresponds to the third opening 343. When the valve core 35 is in the fourth position, the first port 3511 corresponds to the fifth opening 345, the third port 3513 corresponds to the first opening 341, the fourth port 3521 corresponds to the fourth opening 344, and the fifth port 3522 corresponds to the third opening 343.

[0106] In this embodiment, both the first three-way hole 351 and the second three-way hole 352 include two interconnected channels. In other embodiments, the first three-way hole 351 can be changed into two non-interconnected first channels and second channels, and the second three-way hole 352 can be changed into two non-interconnected third channels and fourth channels. When the valve core 35 is in the third position, the first opening 341 and the second opening 342 are connected through the first channel, and the third opening 343 and the sixth opening 346 are connected through the fourth channel. When the valve core 35 is in the fourth position, the first opening 341 and the fifth opening 345 are connected through the second channel, and the third opening 343 and the fourth opening 344 are connected through the third channel.

[0107] In this embodiment, two low-oxygen interfaces 201 and two low-oxygen through holes 101 are provided. Correspondingly, two first openings 341, two second openings 342, two fifth openings 345, and two first three-way holes 351 are provided. When the valve core 35 is in the third position, the two low-oxygen interfaces 201 and the two low-oxygen through holes 101 are connected through the two first three-way holes 351 respectively. When the valve core 35 is in the fourth position, the two low-oxygen interfaces 201 are connected to the outside of the container 10 through the two first three-way holes 351 respectively. The function of providing two low-oxygen interfaces 201 and two low-oxygen through holes 101 has been explained in the first embodiment above, and will not be repeated here.

[0108] As shown in Figure 19, the valve core 35 is provided with a third mark 353 and a fourth mark 354 arranged along its circumferential direction. The converter 30 also includes an indicator mark 36 located on one side of the valve core 35 in the radial direction to point to the third mark 353 or the fourth mark 354. When the valve core 35 is in the third position, the indicator mark 36 points to the third mark 353. When the valve core 35 is in the fourth position, the indicator mark 36 points to the fourth mark 354.

[0109] The converter 30 includes a fixing plate 32 fixedly arranged relative to the container 10, and the indicating mark 36 is arranged on the fixing plate 32. The indicating mark 36 can specifically be an arrow.

[0110] The functions of the third mark 353 and the fourth mark 354 are to show the internal state of the container 10. When the converter 30 is in the first state, the valve core 35 is in the third position, and the indicating mark 36 points to the third mark 353. When the converter 30 is in the second state and the valve core 35 is in the fourth position, the indicating mark 36 points to the fourth mark 354. Thus, by observing whether the indicating mark 36 points to the third mark 353 or the fourth mark 354, the user can understand the internal state of the container 10.

[0111] When the indicating mark 36 points to the third mark 353, it indicates that the interior of the container 10 is a low-oxygen area. When the indicating mark 36 points to the fourth mark 354, it indicates that the interior of the container 10 is a high-oxygen area.

[0112] In this embodiment, the third mark 353 is specifically the Chinese character "low", and the fourth mark 354 is specifically the Chinese character "high". It can be understood that the third mark 353 and the fourth mark 354 can also use other symbols, as long as the two are distinguishable. For example, the third mark 353 can be the letter "L", the fourth mark 354 can be the letter "H", or the third mark 353 can be the number "1", and the fourth mark 354 can be the number "2".

[0113] The valve seat 31 includes an extending portion 355 extending outside the seat body 34, and an anti-slip pattern 3351 is formed on the outer periphery of the extending portion 355. When the converter 30 is in use, the user manually twists the extending portion 355 to switch between the third position and the fourth position, and the anti-slip pattern 3351 can prevent slipping when the extending portion 355 is twisted.

[0114] In the refrigeration device 100 provided by the third embodiment of the present application, the oxygen control module 20 can be arranged inside the container 10. In this way, the oxygen concentration inside the container can be adjusted more quickly and directly, enabling a high-oxygen or low-oxygen atmosphere to quickly distribute to every corner inside the container 10, improving the speed of adjusting the oxygen content inside the container 10, and thus more quickly meeting the storage requirements. The built-in oxygen control module 20 makes the overall structure of the device more compact and integrated, reduces the complexity of external connections and pipelines, lowers the installation and maintenance costs. At the same time, this also avoids the risk of leakage or failure caused by external pipeline failures, thereby improving the stability and safety of the device operation. Placing the oxygen control module 20 inside the container 10 can improve the efficiency and accuracy of oxygen adjustment, optimize space utilization, simplify the device design, and enhance stability and safety.

[0115] The oxygen control module 20 may include an electrolyte containment chamber, a first electrode, and a second electrode, with the first and second electrodes at least partially exposed in the electrolyte containment chamber. The oxygen control module 20 is configured to generate a high-oxygen atmosphere or a low-oxygen atmosphere at the first electrode via an electrochemical reaction. The oxygen control module 20 is disposed inside the container 10 to supply a high-oxygen atmosphere or a low-oxygen atmosphere to the container 10.

[0116] Referring to Figures 20-21, in one embodiment of this application, container 10 may include a first container 11 and a second container 12.

[0117] The oxygen regulation and control module 20 is also configured to form a high-oxygen atmosphere or a low-oxygen atmosphere at the second electrode, opposite to that at the first electrode, through an electrochemical reaction. The oxygen regulation module 20 is disposed inside the first container 11 to supply the high-oxygen atmosphere or low-oxygen atmosphere at the first electrode to the first container 11. An oxygen regulation passage 23 is provided between the oxygen regulation module 20 and the second container 12. The oxygen regulation module 20 supplies the high-oxygen atmosphere or low-oxygen atmosphere at the first or second electrode to the interior of the second container 12 through the oxygen regulation passage 23.

[0118] When the oxygen control module 20 supplies a high-oxygen atmosphere or a low-oxygen atmosphere at the first electrode to the inside of the second container 12 through the oxygen regulation circuit 23, the first container 11 and the second container 12 can form the same or similar oxygen atmosphere. That is, the first container 11 and the second container 12 can both be high-oxygen atmosphere or both are low-oxygen atmosphere, and the oxygen concentration of the first container 11 and the second container 12 can be the same or different.

[0119] By creating the same type (high oxygen or low oxygen) atmosphere in the first container 11 and the second container 12, the oxygen regulation space of the oxygen control module 20 is expanded, while allowing for differences in oxygen concentration. This design can better address the sensitivity of different items to oxygen concentration during storage, creating storage environments with different oxygen concentrations to effectively extend the shelf life of different foods or items, reduce oxidation or other adverse reactions, and provide flexibility and efficiency for storing items with different needs at the same time, thus optimizing the management and control of the storage environment.

[0120] When the oxygen control module 20 supplies a high-oxygen atmosphere or a low-oxygen atmosphere at the second electrode to the inside of the second container 12 through the oxygen regulation circuit 23, the first container 11 and the second container 12 form opposite oxygen atmospheres. That is, if a low-oxygen atmosphere is formed in the first container 11, a high-oxygen atmosphere is formed in the second container 12, and if a high-oxygen atmosphere is formed in the first container 11, a low-oxygen atmosphere is formed in the second container 12.

[0121] Since the process of generating high-oxygen and low-oxygen atmospheres through electrochemical reactions in the oxygen control module 20 usually occurs simultaneously, achieving opposite atmosphere regulation for the two containers with a single oxygen control module 20 saves the need for multiple regulation devices, reduces energy consumption and equipment complexity, and is more environmentally friendly, with lower energy consumption and higher overall equipment efficiency. This opposite and complementary atmosphere regulation method allows the first container 11 and the second container 12 to store items requiring drastically different oxygen concentration environments. For example, one container 10 can be used to store food requiring a low-oxygen atmosphere, while the other container 10 can be used to store food requiring a high-oxygen atmosphere. In this way, users can simultaneously meet the oxygen concentration requirements of different items in one device, improving the applicability and functional versatility of the equipment.

[0122] Referring to Figures 20 and 21, in one embodiment of this application, the oxygen control module 20 may include a housing 21. A first electrode, a second electrode, and an electrolyte containment cavity may all be disposed within the housing 21. The oxygen control module 20 includes at least one anode conductive plate and at least one cathode conductive plate. The first electrode and the second electrode may be respectively composed of a cathode conductive plate and an anode conductive plate. The electrolyte containment cavity may store electrolyte. The anode conductive plate and the cathode conductive plate may be respectively disposed within the electrolyte containment cavity and at least partially immersed in the electrolyte. The anode conductive plate and the cathode conductive plate may be arranged alternately. A waterproof and breathable composite layer may be disposed 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, allowing oxygen in the air to pass through the composite layer into the electrolyte containment cavity, while preventing electrolyte from permeating out of the electrolyte containment cavity through the composite layer. The cathode conductive plate can adsorb oxygen in the gas. The electrical terminals on the anode conductive plate may extend out of the housing 21 and be electrically connected to the power anode. The cathode conductive plate is electrically connected to the power cathode.

[0123] The housing 21 may be provided with a gas channel connecting the electrolyte containment cavity and the outside of the housing 21. During operation, oxygen in the air entering the housing 21 from the outside space through the gas channel passes through the composite layer and reaches the surface of the cathode conductive plate with the negative electrode. Under the action of a DC electric field, an oxygen dissolution reaction occurs on the surface of the cathode conductive plate, adsorbing oxygen and creating a low-oxygen atmosphere at the cathode conductive plate. Subsequently, a reverse reaction occurs on the anode conductive plate to produce oxygen, creating a high-oxygen atmosphere at the anode conductive plate. The high-oxygen atmosphere or low-oxygen atmosphere formed by the electrochemical reaction can be transported into the container 10 to create a high-oxygen atmosphere or low-oxygen atmosphere inside the container 10.

[0124] Referring to Figures 20 to 22, in one embodiment of this application, the housing 21 may have a ventilation opening 22 communicating with the interior of the first container 11. A high-oxygen atmosphere or a low-oxygen atmosphere at the first electrode is supplied to the interior of the first container 11 through the ventilation opening 22. The oxygen regulation path 23 includes an interface 231 disposed in the housing 21 and a gas port 232 disposed in the second container 12. A high-oxygen atmosphere or a low-oxygen atmosphere at the second electrode is supplied to the interior of the second container 12 through the interface 231 and the gas port 232.

[0125] Through a flexible design of the atmosphere supply path, the oxygen control module 20 generates opposite oxygen atmospheres at different electrodes, which can be transmitted to the two containers separately via gas paths. This configuration can meet the specific atmosphere requirements of different items, broadening the application range of the equipment. Through the ventilation opening 22 on the housing 21, the high-oxygen or low-oxygen atmosphere generated by the first electrode can directly enter the first container 11. Simultaneously, the oxygen regulation path 23, through the interface 231 on the housing 21 and the gas port 232 on the second container 12, transmits the high-oxygen or low-oxygen atmosphere from the second electrode to the second container 12. This design ensures a smooth atmosphere transmission path, contributing to efficient atmosphere transmission and uniform distribution. It also ensures the atmosphere independence between the first container 11 and the second container 12, maintaining a clear and independent transmission path, avoiding atmosphere cross-interference, and guaranteeing the atmosphere stability inside both containers.

[0126] Referring to Figures 23 or 24, and Figure 21, in some embodiments of this application, the oxygen control module 20 is disposed within the first container 11. Air from the first container 11 enters the housing 21 through the ventilation opening 22 and undergoes an electrochemical reaction at the first electrode, creating a low-oxygen atmosphere at the first electrode. Simultaneously, an electrochemical reaction occurs at the second electrode, creating a high-oxygen atmosphere at the second electrode.

[0127] The ventilation opening 22 may include multiple openings or a single large opening. Air from the first container 11 can enter the first electrode inside the shell 21 through a portion of the ventilation opening 22. The electrochemical reaction occurring at the first electrode adsorbs oxygen from the air, reducing the oxygen content and creating a low-oxygen atmosphere at the first electrode. This low-oxygen atmosphere can then flow back into the first container 11 through the remaining openings of the ventilation opening 22. This cycle gradually reduces the oxygen content within the first container 11, thus creating a low-oxygen atmosphere within it.

[0128] While an electrochemical reaction occurs at the first electrode, creating a low-oxygen atmosphere, an electrochemical reaction also occurs at the second electrode, creating a high-oxygen atmosphere. The high-oxygen atmosphere at the second electrode can be pure oxygen, equivalent to oxygen dissolved at the first electrode being adsorbed through an electrochemical reaction and then released at the second electrode through the same reaction. This high-oxygen atmosphere at the second electrode is then transported to the second container 12 via oxygen regulating path 23, thereby enabling the formation of a high-oxygen atmosphere within the second container 12.

[0129] In this way, the oxygen content in the first container 11 can be reduced by the airflow circulation between the first container 11 and the oxygen control module 20, while the oxygen adsorbed from the first container 11 can be used to increase the oxygen content in the second container 12. Placing the oxygen control module 20 inside the first container 11 facilitates gas circulation between the oxygen control module 20 and the first container 11, thus simplifying the gas circulation structure between them. Furthermore, only one path is needed between the oxygen control module 20 and the second container 12 to supply oxygen; no additional loop is required, simplifying the oxygen regulation path 23 between the second container 12 and the oxygen control module 20, resulting in a more compact overall structure.

[0130] Referring to Figures 25, 26, or 27, in some embodiments of this application, the oxygen regulating path 23 may include an outlet path 233 and a return path 234. The outlet path 233 includes an outlet 2321 disposed on the wall of the second container 12 or inside the second container 12, and a first interface 2311 disposed on the housing 21. The return path 234 includes a return port 2322 disposed on the wall of the second container 12 or inside the second container 12, and a second interface 2312 disposed on the housing 21. Air from the second container 12 enters the housing 21 through the outlet 2321 and the first interface 2311, and undergoes an electrochemical reaction at the second electrode, creating a low-oxygen atmosphere at the second electrode. Simultaneously, an electrochemical reaction occurs at the first electrode, creating a high-oxygen atmosphere at the first electrode. The low-oxygen atmosphere at the second electrode is supplied to the interior of the second container 12 through the second interface 2312 and the return port 2322.

[0131] Through the exhaust gas path 233 and the return gas path 234, a gas circulation path can be formed between the second container 12 and the oxygen control module 20, enabling the oxygen control module 20 to adsorb oxygen from the air in the second container 12, thereby reducing the oxygen content in the second container 12 and creating a low-oxygen atmosphere inside the second container 12. Furthermore, the oxygen control module 20 can deliver the generated oxygen to the first container 11 through the ventilation opening 22, thereby increasing the oxygen content in the first container 11 and creating a high-oxygen atmosphere inside the first container 11.

[0132] Referring to Figures 23, 25, and 26, in some embodiments of this application, the first container 11 is disposed within the second container 12, or the second container 12 is disposed within the first container 11. By nesting the two containers, the overall volume of the device can be effectively reduced. The nested structure design allows the oxygen control module 20 to distribute the atmosphere to the two containers more efficiently. Because the two containers are closely connected, the atmosphere transmission path is shortened, which makes the generation and supply of high-oxygen or low-oxygen atmosphere faster and more efficient, while reducing the complexity of the gas path.

[0133] Referring to Figures 24 and 27, in some embodiments of this application, the first container 11 and the second container 12 can be arranged side by side, either vertically or horizontally.

[0134] Referring to FIG28, in one embodiment of this application, container 10 includes a first container 11 and a second container 12. An oxygen control module 20 is disposed within the first container 11 to supply a high-oxygen atmosphere or a low-oxygen atmosphere from the first electrode to the first container 11. A gas flow path 24 is provided between the first container 11 and the second container 12. The high-oxygen atmosphere or low-oxygen atmosphere inside the first container 11 is supplied to the second container 12 through the gas flow path 24.

[0135] By setting up a gas flow path 24, gas exchange is achieved between the first container 11 and the second container 12, thereby adjusting the oxygen content of the second container 12. This design differs from the method described above, which uses a single oxygen control module 20 to adjust the oxygen content of each container separately. Since only one oxygen control module 20 needs to operate, the oxygen concentration in the second container 12 can be efficiently adjusted by sharing the high-oxygen or low-oxygen atmosphere in the first container 11 through the gas flow path 24, avoiding the additional energy consumption caused by adjusting the atmosphere of each container individually. Through the gas flow path 24 between the first container 11 and the second container 12, both high-oxygen and low-oxygen atmospheres can be quickly propagated to the second container 12, enabling both containers to quickly reach the required oxygen concentration, improving the response speed of atmosphere adjustment, and meeting diverse storage needs.

[0136] Referring to FIG29, in one embodiment of this application, the refrigeration device 100 includes a storage space located outside the container 10. The refrigeration device 100 also includes a gas supply passage 25 that connects the internal space of the housing 21 with the storage space or the external space of the refrigeration device 100. Air from the storage space or air from outside the refrigeration device 100 enters the housing 21 through the gas supply passage 25 and undergoes an electrochemical reaction at the second electrode to form a low-oxygen atmosphere at the second electrode. Simultaneously, an electrochemical reaction occurs at the first electrode to form a high-oxygen atmosphere at the first electrode. The housing 21 has a ventilation opening 22 that communicates with the interior of the container 10. The high-oxygen atmosphere at the first electrode is supplied to the interior of the container 10 through the ventilation opening 22.

[0137] Unlike the aforementioned method where the oxygen control module 20 adsorbs oxygen from the air inside the container 10 to generate a high-oxygen atmosphere, this embodiment introduces air from the storage space of the refrigeration device 100 or from outside into the housing 21 via the gas supply path 25. An electrochemical reaction occurs at the second electrode to generate a low-oxygen atmosphere, while a high-oxygen atmosphere is generated at the first electrode. This high-oxygen atmosphere is then delivered to the interior of the container 10 through the ventilation opening 22. Compared to a closed system, this design utilizes external air resources to enhance the flexibility of atmosphere generation.

[0138] Referring to Figures 1 and 30, in one embodiment of this application, the refrigeration device 100 includes a housing 40, a storage compartment 50 formed within the housing 40, and a door 60 for opening and closing the storage compartment 50. A container 10 is disposed within the storage compartment 50. The container 10 includes a cylindrical body 13 and a drawer 14. The cylindrical body 13 has a front opening 131. The drawer 14 is removably installed within the cylindrical body 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 cylindrical body 13.

[0139] Container 10 employs a cylindrical body 13 and a drawer 14 structure. The drawer 14 can be pulled out through an opening at the front of the cylindrical body 13. Users can easily retrieve or place stored items from the storage compartment 50 without fully opening the entire container. This design not only simplifies the process of retrieving and placing items but also reduces the chance of gas loss when the container is opened, maintaining a stable internal environment for container 10. Because of the drawer 14 design, users can easily pull out the drawer 14 for cleaning and maintenance. Compared to traditional fixed containers, the drawer 14 design not only improves operational flexibility but also facilitates the timely removal of any residual dirt and impurities, ensuring the equipment is always in good operating condition. Furthermore, the cylindrical seal 15 can be easily replaced and inspected, extending the equipment's service life.

[0140] Referring to FIG30, in one embodiment of this application, a cylinder seal 15 is provided between the front panel of the drawer 14 and the front wall of the cylinder 13. The cylinder seal 15 is used to seal the gap between the front panel of the drawer 14 and the front wall of the cylinder 13.

[0141] The front panel of drawer 14 is sealed to the front wall of cylinder 13 by a cylinder seal 15. This seal effectively fills the gap between the front panel of drawer 14 and the front wall of cylinder 13, preventing gas leakage. Sealing is crucial for maintaining a low-oxygen environment inside container 10. By using the cylinder seal 15, oxygen is prevented from seeping in through the gap, thus avoiding affecting the oxygen concentration inside the container. This design significantly improves oxygen regulation, allowing stored items to remain in a stable low-oxygen environment for extended periods, extending their shelf life. When drawer 14 is closed, the cylinder seal 15 between the front panel and the front wall of cylinder 13 ensures that the gas is completely sealed inside the container, effectively preventing the infiltration of external oxygen. By maintaining the stability of the internal gas environment, container 10 can continuously operate at high efficiency, reducing the need for frequent adjustments to oxygen concentration and thus improving the overall energy efficiency of the equipment.

[0142] In one embodiment of this application, the storage compartment 50 is a refrigeration compartment. The container 10 is located within the refrigeration compartment, enabling the oxygen control module 20 to work in conjunction with the refrigeration system, ensuring effective control of the temperature and gas environment within the container 10. Through a rational layout of the ventilation ports 232 and the gas flow design, more precise oxygen concentration regulation can be achieved in low-temperature environments, extending the shelf life of stored items, especially showing a significant preservation effect on oxygen-sensitive ingredients (such as fruits, vegetables, and meats).

[0143] Referring to Figures 20 and 30, in one embodiment of this application, the oxygen control module 20 is installed on the left or right side of the drawer 14. Installing the oxygen control module 20 on the left or right side of the drawer 14 optimizes the internal space layout of the cylinder 13 and avoids the oxygen control module 20 occupying excessive storage space within the cylinder 13. The placement of the oxygen control module 20 makes its maintenance and replacement more convenient, and also enables the atmosphere control system to operate efficiently.

[0144] In this application, the vertical direction refers to the height direction of the refrigeration equipment 100, the front-back 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. The opening of the storage compartment faces forward.

[0145] The refrigeration equipment 100 in this application refers to a mechanical system or device used to lower and control the temperature of an object or space. Based on its ability to lower the temperature of a space or object, the refrigeration equipment 100 is widely used in homes, businesses, and other locations. In one embodiment of this application, the refrigeration equipment 100 may refer to a refrigerator. Refrigerators are one of the most common refrigeration equipment 100s in homes, used to preserve food, prevent spoilage, and extend its shelf life. In one embodiment of this application, the refrigeration equipment 100 may refer to a display case. Display cases are widely used in commercial environments, primarily for displaying and preserving food such as beverages, cooked food, pastries, and dairy products. These devices not only maintain food at a suitable temperature but also optimize product display, attracting customers to purchase. Display cases have diverse designs and structures, and can be broadly categorized into several types based on usage needs and occasions, including freestanding, tabletop, hanging, and built-in types. Display case components can maintain food at safe and suitable temperatures, extending its shelf life and preventing spoilage. Its transparent design makes the food clearly visible, allowing customers to easily view and select the products they want, thus improving shopping efficiency.

[0146] In summary, the refrigeration equipment 100 of this application can solve the problem that existing designs lack control over oxygen concentration and cannot provide the necessary oxygen environment for food.

[0147] By adopting the technical solution of this application, the oxygen control module 20 can be installed inside the container 10, enabling faster and more direct adjustment of the oxygen concentration within the container. This allows for the rapid distribution of high-oxygen or low-oxygen atmospheres to every corner of the container 10, increasing the speed of oxygen content adjustment and thus meeting storage needs more quickly. The built-in oxygen control module 20 makes the overall structure of the equipment more compact and integrated, reducing the complexity of external connections and piping, lowering installation and maintenance costs. Simultaneously, it avoids the risk of leakage or failure caused by external pipeline malfunctions, thereby improving the stability and safety of equipment operation. Placing the oxygen control module 20 inside the container 10 improves the efficiency and accuracy of oxygen regulation, optimizes space utilization, simplifies equipment design, and enhances stability and safety.
