DETAILED DESCRIPTION

[0025] The patent will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the patent, and the changes made by those of ordinary skill in the art to the structure, method, or function of these embodiments are included within the scope of the patent.

[0026] With reference to Figures 1 to 5 The present application provides a refrigeration device 100. The refrigeration device 100 comprises an oxygen adjusting container 1 and an oxygen adjusting module 2 arranged outside the oxygen adjusting container 1. The oxygen adjusting module 2 is used to adjust the oxygen content in the oxygen adjusting container 1. The oxygen adjusting module 2 comprises an air outlet 21 and an air return port 22. The wall of the oxygen adjusting container 1 is provided with an air exchange inlet 11 communicating with the air outlet 21. The wall of the oxygen adjusting container 1 is provided with an air exchange outlet 12 communicating with the air return port 22. The oxygen adjusting container 1 further comprises a gas guiding structure 13 for guiding the gas entering the oxygen adjusting container 1 from the air exchange inlet 11 to the area away from the air exchange outlet 12.

[0027] The air outlet 21 and the air return port 22 of the oxygen adjusting module 2 are connected to the air exchange inlet 11 and the air exchange outlet 12 in the oxygen adjusting container 1 through reasonable layout, forming a closed-loop gas circulation system. By arranging the gas guiding structure 13, the gas entering the container can be effectively guided from the air exchange inlet 11 to the area away from the air exchange outlet 12, avoiding the short circuit phenomenon of the gas in the oxygen adjusting container 1, ensuring that the gas can be uniformly distributed and flow through the entire inside of the oxygen adjusting container 1, reducing the stagnation and ineffective circulation of the gas in the container, reducing the oxygen adjusting time, and greatly improving the oxygen adjusting efficiency.

[0028] With reference to Figure 5 In an embodiment of the present application, the wall is recessed to form a groove 131. The groove 131 comprises a first groove end 1311 communicating with the air exchange inlet 11. The groove 131 further comprises a second groove end 1312 away from the air exchange outlet 12. The oxygen adjusting container 1 comprises a groove cover 132 covering the opening of the groove 131. The groove 131 and the groove cover 132 form a gas guiding channel. The groove cover 132 or the groove 131 wall is formed with a gas guiding outlet 134 near the second groove end 1312. The gas guiding outlet 134 communicates with the inside of the oxygen adjusting container 1.

[0029] The combination of the groove 131 and the groove cover 132 forms a relatively independent gas guiding channel, so that after the gas enters the oxygen adjusting container 1, it first flows along the gas guiding channel, ensuring that the gas can be orderly guided to the area away from the air exchange outlet 12, avoiding the gas flowing back to the air exchange outlet 12 immediately after entering the oxygen adjusting container 1, thereby realizing the full circulation and distribution of the gas.

[0030] The groove 131 is formed by recessing the wall of the oxygen adjusting container 1, which is stable and durable. This integrated structure design modifies the wall of the container itself, reducing additional components, the complexity of the mold and the production process, and not only reducing the production steps, but also reducing the production cost, improving the production efficiency, and making the production process simpler and more efficient. In addition, the design of the groove 131 can integrate the gas guide channel on the wall of the oxygen adjusting container 1, so that the gas guide channel is embedded in the wall of the container, reducing the occupation of the internal and external space of the oxygen adjusting container 1.

[0031] Referring to Figure 5 In an embodiment of the present application, the groove 131 is formed by recessing the wall of the oxygen adjusting container 1 inward. The groove cover 132 is arranged outside the oxygen adjusting container 1. The groove cover 132 is arranged outside the oxygen adjusting container 1, and the complete gas guide channel can be formed by simply covering the groove 131, which reduces the complexity of manufacturing and assembly. Since the groove cover 132 is located outside the oxygen adjusting container 1, when maintenance or maintenance of the gas guide channel is required, the operator can easily remove or replace the groove cover 132 without entering the interior of the oxygen adjusting container 1. This external detachable design reduces the complexity of the maintenance operation and improves the convenience of maintenance.

[0032] Referring to Figure 5 In an embodiment of the present application, the gas guide structure 13 further comprises a cover seal 133 arranged between the groove cover 132 and the wall. The cover seal 133 can be annular and can be made of rubber or other materials. The cover seal 133 is used to seal the gap between the groove cover 132 and the wall. The design of the cover seal 133 effectively fills the gap between the groove cover 132 and the wall, ensuring the airtightness of the entire gas guide channel. Through the cover seal 133, gas leakage can be prevented at the connection between the groove 131 and the groove cover 132.

[0033] Referring to Figure 3 and Figure 5 In an embodiment of the present application, the distance between the gas guide outlet 134 and the gas exchange outlet 12 is greater than 1.5*L. L is the sum of the diameters of the gas exchange inlet 11 and the gas exchange outlet 12.

[0034] When the distance between the gas guide outlet 134 and the gas exchange outlet 12 is close, the gas may flow directly from the gas exchange inlet 11 to the gas exchange outlet 12 after entering the container, causing part of the gas to not be effectively diffused, resulting in a short circuit phenomenon, which will affect the uniform distribution of the gas inside the oxygen adjusting container 1, thereby reducing the oxygen adjusting efficiency. By designing the distance between the gas guide outlet 134 and the gas exchange outlet 12 to be greater than 1.5 times L, the short circuit flow of the gas can be effectively avoided, forcing the gas to pass through a longer path in the container, thereby better uniformly distributed.

[0035] Referring to Figure 6In an embodiment of the present application, the oxygen adjusting container 1 comprises a wind baffle 135 arranged between the air exchange inlet 11 and the air exchange outlet 12.

[0036] Unlike the design of the above-mentioned embodiment in which the air guide structure 13 is formed by the groove 131 and the groove cover 132, the air guide structure 13 in the present embodiment is formed by the wind baffle 135. The arrangement of the wind baffle 135 effectively prevents the gas from flowing directly from the air exchange inlet 11 to the air exchange outlet 12. By guiding the gas to flow within the oxygen adjusting container 1 through the wind baffle 135, the gas can be more evenly distributed within the container, thereby ensuring that the oxygen concentration in each region is more balanced and improving the overall oxygen adjusting effect.

[0037] With reference to Figure 3 and Figure 6 In an embodiment of the present application, the wind baffle 135 and the wall of the oxygen adjusting container 1 form a wind baffle channel 1351. The air inlet end 1352 of the wind baffle channel 1351 is in communication with the air exchange inlet 11. The air outlet end 1353 of the wind baffle channel 1351 is away from the air exchange outlet 12.

[0038] The wind baffle channel 1351 formed by the wind baffle 135 and the wall can force the gas to flow along a set path, avoiding the direct flow of the gas from the air exchange inlet 11 to the air exchange outlet 12. Since the air inlet end 1352 and the air outlet end 1353 are arranged at different positions, the gas must flow along the wind baffle channel 1351, ensuring that the gas passes through multiple regions within the oxygen adjusting container 1. This design effectively prevents the direct backflow of the gas, thereby ensuring the uniform distribution of the gas within the container and improving the oxygen adjusting effect. The wind baffle channel 1351 is relatively simple in design and can be achieved through the modular installation of the wind baffle 135. This design is convenient for production, assembly, and later maintenance, reducing production costs.

[0039] With reference to Figure 4 In an embodiment of the present application, the oxygen adjusting module 2 comprises a shell 23 and a deoxygenation assembly arranged in the shell 23. The shell 23 forms an air outlet 21 and an air return port 22. The deoxygenation assembly is used to reduce the oxygen content of the gas entering the shell 23 from the air return port 22. The air outlet 21 is used to deliver the low-oxygen-content gas in the shell 23 to the oxygen adjusting container 1, thereby reducing the oxygen content in the oxygen adjusting container 1.

[0040] The oxygen adjusting module 2 forms a closed-loop circulation system for the gas through the air return port 22 and the air outlet 21. The gas is continuously circulated between the container and the oxygen adjusting module 2. The deoxygenation assembly processes the recovered gas to reduce its oxygen content, and then sends it back to the container. Through repeated circulation, the oxygen content in the oxygen adjusting container 1 can be quickly and effectively reduced, and the oxygen adjusting efficiency can be improved. The shell 23 and the deoxygenation assembly of the oxygen adjusting module 2 are designed in a modular manner, which not only makes the production and assembly of the equipment more convenient, but also facilitates later maintenance and replacement.

[0041] The specific composition of the oxygen-reducing assembly can adopt existing oxygen-reducing technology.

[0042] For example, the oxygen-reducing assembly can include an oxygen generation box, at least one anode conductive plate, and at least one cathode conductive plate. The oxygen generation box can have an oxygen generation chamber for storing electrolyte, and the anode conductive plate and the cathode conductive plate can be arranged in the oxygen generation chamber and at least partially immersed in the electrolyte, respectively. The anode conductive plate and the cathode conductive plate can be arranged in a spaced manner. One side or both sides of the cathode conductive plate can be provided with a waterproof and breathable composite layer. The cathode conductive plate and the composite layer together form an independent oxygen generation film, so that oxygen in the air can pass through the composite layer into the oxygen generation chamber, and the electrolyte cannot seep out of the oxygen generation chamber through the composite layer. The side of the cathode conductive plate provided with the composite layer at least partially exposes outside the oxygen generation box to adsorb oxygen in the air. The oxygen generation box is provided with an air outlet channel communicating with the oxygen generation chamber. The power connection end on the anode conductive plate is led out of the oxygen generation box and electrically connected to the anode of the power supply. The cathode conductive plate is electrically connected to the cathode of the power supply. When working, the oxygen in the air entering the shell from the air inlet 22 passes through the composite layer to the surface of the cathode conductive plate with a negative electrode, and a dissolved oxygen reaction occurs on the surface of the cathode conductive plate under the action of a direct current electric field, and then a reverse reaction occurs on the anode conductive plate to generate pure oxygen. The pure oxygen generated can be delivered to other storage spaces of the refrigeration equipment 100 through the air outlet channel, or can be directly discharged. The low-oxygen-content air after the dissolved oxygen reaction can be discharged from the air outlet 21 of the shell into the oxygen adjusting container 1, thereby reducing the oxygen content in the oxygen adjusting container.

[0043] In addition, oxygen molecules in the gas can also be separated by physical methods to reduce the oxygen content, or oxygen can be adsorbed from the gas by chemical methods to reduce the oxygen content. For example, the oxygen-reducing assembly can include an oxygen separation membrane. The oxygen separation membrane is a specially designed selective membrane structure that can pass through oxygen molecules during gas flow. The material of the membrane has high selectivity for oxygen and low permeability for other gases, so the oxygen content in the gas can be reduced by physical separation. For another example, the oxygen-reducing assembly can include a specific adsorption material (such as zeolite, carbon molecular sieve), which selectively adsorbs oxygen molecules to remove oxygen from the circulating gas. The oxygen-reducing assembly can also include a vacuum pump. The vacuum pump is used to form a low-pressure environment in the system to promote the discharge of oxygen and further improve the oxygen-reducing effect.

[0044] Referring to Figure 1 and Figure 7In an embodiment of the present application, the refrigeration device 100 comprises a cabinet 3, a storage compartment 4 formed in the cabinet 3, and a door 5 for opening and closing the storage compartment 4. The oxygen adjusting container 1 is arranged in the storage compartment 4. The oxygen adjusting container 1 comprises a barrel 136 and a drawer 137. The barrel 136 has a front opening 1361. The drawer 137 is mounted in the barrel 136 through the front opening 1361 and can be pulled out. The front plate 1371 of the drawer is used to open and close the front opening 1361 of the barrel 136.

[0045] The oxygen adjusting container 1 adopts the barrel 136 and drawer 137 structure design, and the drawer 137 can be pulled out through the opening at the front of the barrel 136. The user can conveniently take out or put in the storage items from the storage compartment 4 without completely opening the entire container. This design not only simplifies the process of taking and placing items, but also reduces the opportunity for gas loss when the container is opened, maintaining the stability of the internal environment of the oxygen adjusting container 1. Since the oxygen adjusting container 1 adopts the drawer 137 design, the user can easily pull out the drawer 137 for cleaning and maintenance. Compared with the traditional fixed container, the drawer 137 design not only improves the flexibility of operation, but also facilitates the timely removal of possible residual dirt and impurities, ensuring that the device is always in good operating condition. In addition, the barrel seal 138 can also be easily replaced and inspected, prolonging the service life of the device.

[0046] Referring to Figure 1 and Figure 7 In an embodiment of the present application, a barrel seal 138 is arranged between the front plate 1371 of the drawer and the front wall of the barrel 136. The barrel seal 138 is used to seal the gap between the front plate 1371 of the drawer and the front wall of the barrel 136.

[0047] The front plate 1371 of the drawer and the front wall of the barrel 136 are sealed by the barrel seal 138, which effectively fills the gap between the front plate 1371 of the drawer and the front wall of the barrel 136, preventing gas leakage. The sealing property is crucial for the oxygen adjusting container 1 to maintain a low-oxygen environment inside. By arranging the barrel seal 138, it can be ensured that oxygen does not penetrate from the gap, avoiding affecting the oxygen concentration inside the container. This design greatly improves the oxygen adjusting effect, allowing the stored items to be in a stable low-oxygen environment for a long time, extending the preservation time. When the drawer 137 is closed, the barrel seal 138 between the front plate and the front wall of the barrel 136 can ensure 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, the oxygen adjusting 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 device.

[0048] Referring to Figure 2 , Figure 3 , Figure 5 , Figure 8In an embodiment of the present application, the oxygen adjusting module 2 is arranged below the cylinder 136. The bottom wall of the cylinder 136 forms the air exchange inlet 11 and the air exchange outlet 12. The air exchange inlet 11 is close to the rear wall of the cylinder 136. The air exchange outlet 12 is close to the left / right wall of the cylinder 136. The rear wall of the cylinder 136 forms a groove 131. The rear wall of the drawer 137 is provided with a first opening 1372 matched with the air guide outlet 134. The bottom wall and the left / right wall of the drawer 137 are provided with a second opening 1373 matched with the air exchange outlet 12.

[0049] The oxygen adjusting module 2 is arranged below the cylinder 136. The air exchange inlet 11 and the air exchange outlet 12 formed by the bottom wall of the cylinder 136 can facilitate the connection between the oxygen adjusting module 2 and the cylinder 136, and ensure smooth gas flow. The layout design that the air exchange inlet 11 is close to the rear wall of the cylinder 136 and the air exchange outlet 12 is close to the left / right wall of the cylinder 136 enables the gas to flow along a longer path inside the cylinder 136, ensuring that the gas can effectively cover the entire container interior, thereby achieving efficient oxygen adjustment.

[0050] By arranging the air exchange inlet 11 near the rear wall of the cylinder 136 and the air exchange outlet 12 near the left / right wall of the cylinder 136, the gas short circuit phenomenon can be effectively prevented. After the gas enters from the inlet, it needs to flow inside the cylinder 136, pass through the groove 131 and the air guide passage, and finally be discharged from the outlet. This design prolongs the flow path of the gas in the container, ensures more uniform distribution of the gas in the container, reduces the phenomenon of uneven gas concentration in local areas, and thus improves the oxygen adjusting effect.

[0051] Referring to Figure 1 The storage compartment 4 is a refrigeration compartment. The oxygen adjusting container 1 is located in the refrigeration compartment, which can enable the oxygen adjusting module 2 to work cooperatively with the refrigeration system, and ensure that the temperature and gas environment in the oxygen adjusting container 1 are effectively controlled. Through reasonable air exchange port layout and gas flow design, more accurate oxygen concentration adjustment can be achieved in a low-temperature environment, the preservation period of stored items is prolonged, and significant preservation effects are achieved for oxygen-sensitive food materials (such as fruits, vegetables and meat).

[0052] In the present application, the up-down direction refers to the height direction of the refrigeration appliance 100, the front-rear direction refers to the depth direction of the refrigeration appliance 100, and the left-right direction refers to the width direction of the refrigeration appliance 100. The storage compartment opening faces forward.

[0053] The refrigeration equipment 100 refers to a mechanical system or equipment for reducing and controlling the temperature of an object or space. Based on the characteristic that the refrigeration equipment 100 can reduce the temperature of a space or an object, the refrigeration equipment 100 is widely used in homes, businesses and the like. In an embodiment of the present application, the refrigeration equipment 100 can refer to a refrigerator. The refrigerator is one of the most common refrigeration equipment 100 in a home, which is used for preserving food, preventing food from deteriorating and prolonging the shelf life thereof. In an embodiment of the present application, the refrigeration equipment 100 can refer to a display cabinet. The display cabinet is widely used in commercial environments, and is mainly used for displaying and preserving food, such as beverages, cooked food, pastries and dairy products and the like. Such equipment not only maintains food at a suitable temperature, but also optimizes the display of goods, attracting customers to purchase. The display cabinet has various designs and structures, and can be roughly classified into several types according to different use requirements and occasions, including a vertical type, a table type, a hanging type and an embedded type and the like. The display cabinet component can maintain food at a safe and suitable temperature, prolong the shelf life of food and prevent food from deteriorating. The transparent design makes food visible at a glance, so that customers can easily view and select the goods they want, improving the shopping efficiency.

[0054] In summary, the refrigeration equipment 100 of the present application can solve the problem that the existing design lacks control of oxygen concentration and cannot provide food materials with the required oxygen environment.

[0055] By adopting the technical solution of the present application, the gas outlet 21 and the gas return outlet 22 of the oxygen adjusting module 2 are connected with the gas exchange inlet 11 and the gas exchange outlet 12 in the oxygen adjusting container 1, forming a closed-loop gas circulation system. By arranging the gas guide structure 13, the gas entering the container can be effectively guided from the gas exchange inlet 11 to an area far away from the gas exchange outlet 12, avoiding the short circuit phenomenon of the gas in the oxygen adjusting container 1, ensuring that the gas can be uniformly distributed and flow through the entire interior of the oxygen adjusting container 1, reducing the stagnation and ineffective circulation of the gas in the container, reducing the oxygen adjusting time and greatly improving the oxygen adjusting efficiency.
