Description

[Technical Field]

[0001] The present invention relates to a freshness-preserving device, and more particularly to a liquid storage device and an electrolytic deoxidation system and refrigerator equipped with the same. [Background technology]

[0002] In some reactors, such as electrochemical reactors for reducing oxygen inside a refrigerator through an electrochemical reaction, an electrolyte is required for the electrochemical reaction process, and gas is generated during the reaction process, which must be discharged to the external environment.

[0003] During the reaction process, a large amount of heat is generated, causing the electrolyte to heat up and evaporate. As a result, the gas emitted from the reaction vessel may contain traces of electrolyte vapor. Most electrolytes are acidic or alkaline solutions and are corrosive. If the gas generated from the reactor is directly emitted into the atmosphere without treatment, it may lead to air pollution, endangering life and health.

[0004] In addition, if the gas generated in the reactor carries the electrolyte vapor, the electrolyte will be gradually lost, resulting in resource waste and increasing production costs.

[0005] For some products, such as fruits and vegetables, it is generally desirable to store them in a low-oxygen, low-temperature environment to extend their shelf life and maintain their freshness.

[0006] To create a low-oxygen, low-temperature freshness-preserving atmosphere, an electrolytic deoxidizer can be installed in a refrigerator. The electrolytic deoxidizer uses an electrochemical reaction to consume oxygen in the storage space. The electrochemical reaction typically takes place in an electrolyte, consuming components of the electrolyte. Therefore, liquid must be added to the electrolytic deoxidizer in a timely manner to ensure the electrochemical reaction is carried out normally.

[0007] Electrolytes are generally corrosive acidic or alkaline liquids. Manually filling the electrolyte poses a safety risk. Furthermore, refilling the electrolytic deoxidation device from the outside requires the electrolytic deoxidation device and its peripheral components to be removed and installed, which complicates the operation process and increases the risk of damage to the device.

[0008] The above information disclosed in the background art of this specification is intended only to deepen understanding of the background art of this application, and may include prior art that is not known to those skilled in the art. Summary of the Invention

[0037] In the liquid storage device with filtration and recovery function of the present invention and the refrigerator equipped therewith, the liquid storage device has a filtering mechanism, and a second liquid storage space communicating with the first liquid storage space of the liquid storage container is formed within the housing of the filtering mechanism, and the filtering part of the filtering mechanism is used to dissolve specific substance components in gas in the external environment into the second liquid storage space and allow it to flow into the first liquid storage space for reuse.Therefore, the present invention provides a liquid storage device with filtration and recovery function that can separate and reuse specific substance components in gas, thereby reducing or avoiding pollution caused by gas emissions and at the same time improving resource utilization efficiency.

[0038] Furthermore, in the liquid storage device with filtration recovery function of the present invention and the refrigerator equipped with the same, the housing is inserted into the first liquid storage space and communicates with the first liquid storage space through the liquid outlet hole at the bottom of the housing, and the liquid in the second liquid storage space flows downward through the liquid outlet hole due to its own gravity and back into the first liquid storage space, thereby making the recovery process of the liquid storage device easy and effective.

[0039] Furthermore, in the liquid storage device with filtration recovery function of the present invention and the refrigerator equipped with the same, the filtering section is a gas conduit that is inserted into the second liquid storage space from the air inlet hole of the housing and extends to the bottom zone of the second liquid storage space, directing external gas to the bottom zone of the second liquid storage space, and the gas flowing out from the gas conduit comes into contact with the liquid in the second liquid storage space as it rises, causing specific substance components in the gas to dissolve in the second liquid storage space, thereby achieving an excellent filtering and purification effect while maintaining an ingenious and simple structure of the liquid storage device.

[0040] Furthermore, in the liquid storage device with filtration and recovery function and the refrigerator equipped with the same of the present invention, the liquid storage device has a filtration and recovery function and outputs liquid to the external environment through a liquid supply port.

[0044] Furthermore, in the electrolytic deoxidation system for a refrigerator and the refrigerator equipped with the same of the present invention, the housing of the filtration mechanism communicates with the liquid storage space, allowing specific substance components dissolved in the housing to enter the liquid storage space.

[0047] 1 is a schematic structural diagram of a liquid storage device 20 with a filtration and recovery function according to one embodiment of the present invention. The liquid storage device 20 of this embodiment has a filtration and recovery function, and separates and recovers specific substance components in gas for reuse.

[0048] Figure 2 is a schematic cross-sectional view of the liquid storage device 20 shown in Figure 1. Figure 3 is a schematic exploded view of the liquid storage device 20 shown in Figure 1. The liquid storage device 20 generally includes a liquid storage container 200 and a filtering mechanism 400.

[0049] Here, a first liquid storage space 210 is formed inside the liquid storage container 200. The first liquid storage space 210 stores a liquid, such as, but not limited to, an electrolyte solution containing a specific component or water.

[0050] The filtering mechanism 400 has a housing 420 and a filtering unit 440. A second liquid storage space 421 is formed in the housing 420 and communicates with the first liquid storage space 210. The filtering unit 440 is disposed in the second liquid storage space 421, and dissolves specific substance components in gas from the external environment into the second liquid storage space 421, which then flows into the first liquid storage space 210 for reuse. A liquid, such as an electrolyte solution or water containing the specific component, is stored in the second liquid storage space 421. Dissolving the specific substance components in gas from the external environment into the second liquid storage space 421 refers to dissolving the specific substance components in the liquid stored in the second liquid storage space 421.

[0051] In this embodiment, the specific substance components are water-soluble substances. In some alternative embodiments, the liquid components stored in the first liquid storage space 210 and the second liquid storage space 421 may be adjusted according to the physicochemical properties of the specific substance components to be separated.

[0052] Since the second liquid storage space 421 is connected to the first liquid storage space 210, specific substance components in the gas from the external environment that are dissolved in the second liquid storage space 421 can enter the first liquid storage space 210 and be reused.

[0053] The liquid storage device 20 of this embodiment has a filtering mechanism 400, and a second liquid storage space 421 communicating with the first liquid storage space 210 of the liquid storage container 200 is formed within the housing 420 of the filtering mechanism 400. The filtering section 440 of the filtering mechanism 400 is used to dissolve specific substance components in gas from the external environment in the second liquid storage space 421 and allow them to flow into the first storage space for reuse. Therefore, the present invention provides a liquid storage device 20 with a filtering and recovery function, which can separate and reuse specific substance components in gas, thereby reducing or avoiding pollution caused by gas emissions and at the same time improving resource utilization efficiency.

[0054] In some alternative embodiments, the housing 420 is inserted into the first liquid storage space 210. For example, the liquid storage container 200 may be substantially rectangular parallelepiped-shaped, and the housing 420 may be inserted as an inner sleeve into the first liquid storage space 210. The examples of shapes of the liquid storage container 200 and the housing 420 are merely schematic and should be easily expanded by those skilled in the art, and are not all listed here.

[0055] Fig. 4 is a schematic structural diagram of the filtering mechanism 400 of the liquid storage device 20 shown in Fig. 1. Fig. 5 is a schematic exploded view of the filtering mechanism 400 of the liquid storage device 20 shown in Fig. 4.

[0056] A liquid outlet hole 422 is provided at the bottom of the housing 420 to communicate with the first liquid storage space 210, allowing the liquid in the second liquid storage space 421 to flow back into the first liquid storage space 210. The liquid outlet hole 422 can function as a "window" for material exchange between the two liquid storage spaces. The liquid outlet hole 422 allows the liquid level in the first liquid storage space 210 to match the liquid level in the second liquid storage space 421, making it easier for the liquid in the second liquid storage space 421 to diffuse into the first liquid storage space 210.

[0057] The housing 420 is disposed in the first liquid storage space 210 and communicates with the first liquid storage space 210 through a liquid outlet hole 422 at the bottom of the housing 420, and allows the liquid in the second liquid storage space 421 to flow downward through the liquid outlet hole 422 and back into the first liquid storage space 210 due to its own gravity, making the recovery process of the liquid storage device 20 easy and effective.

[0058] In some alternative embodiments, the housing 420 is further provided with an air inlet hole 423 for inputting gas from the external environment. The air inlet hole 423 is provided at the top of the housing 420, and may be located, for example, in a tank cover of the housing 420, thereby preventing leakage of the liquid stored in the second liquid storage space 421. In some alternative embodiments, the air inlet hole 423 is provided at a side wall of the housing 420 and may be higher than the normal liquid level of the second liquid storage space 421.

[0059] The filtering section 440 is a gas conduit that extends from the air inlet hole 423 to the second liquid storage space 421 to the bottom zone of the second liquid storage space 421, guiding external gas to the bottom zone of the second liquid storage space 421 and dissolving specific substance components in the gas from the external environment into the second liquid storage space 421 during the gas rising process. By extending the gas conduit to the bottom zone of the second liquid storage space 421, the gas conduit can transport gas from the external environment deep into the liquid stored in the second liquid storage space 421, and can extend the gas flow path within the second liquid storage space 421.

[0060] The filtering section 440 is a gas conduit, and extends from the air inlet hole 423 of the housing 420 to the second liquid storage space 421, down to the bottom zone of the second liquid storage space 421, guiding gas from the external environment to the bottom zone of the second liquid storage space 421, allowing the gas flowing out of the gas conduit to fully come into contact with the liquid in the second liquid storage space 421 as it rises, so that specific substance components in the gas can be dissolved in the second liquid storage space 421, thereby enabling the liquid storage device 20 to have an excellent filtering and purification effect while having an ingenious and simple structure.

[0061] The gas conduit of this embodiment is a straight pipe with both ends open, which allows easy gas inlet and outlet, has a simple structure, and provides excellent gas conduction effect.

[0062] In some alternative embodiments, the shape of the gas conduit may be modified to a vertical curved hook-shaped pipe, with a straight pipe section extending to the bottom zone of the second liquid storage space 421 and a curved pipe section that curves and extends upward from the end of the straight pipe section. The end of the curved pipe section is slightly higher than the end of the straight pipe section and is used to guide the gas flowing through it upward.

[0063] That is, the gas conduit of this embodiment may have a vertical curved hook shape, with the straight section like an umbrella pole and the curved section like an umbrella handle connected to the end of the umbrella pole. The curved section curves upward from the end of the straight section, so that the gas flowing out of the gas conduit is guided to flow upward, making the gas movement direction clearer. The end of the curved section is slightly higher than the end of the straight section, which means that the end of the curved section is still located in the bottom zone of the second liquid storage space 421, so that the gas flow path during the dissolution process is not significantly shortened.

[0064] In some alternative embodiments, the housing 420 further includes an air outlet hole 424, which is used to discharge the gas from which the specific substance components have been separated and which flows through the gas conduit and the second liquid storage space 421. The air outlet hole 424 may be located at the top of the housing 420, for example, on the tank cover of the housing 420. The air outlet hole 424 may discharge the filtered gas to the external environment, for example, the air in the external environment. In some embodiments, the air inlet hole 423 and the air outlet hole 424 are each circular openings. In this embodiment, the air inlet hole 423 and the air outlet hole 424 are each tubular through-holes. Here, the hole wall of the tubular hole of the air inlet hole 423 extends continuously downward into the second liquid storage space 421 and functions as a gas conduit. In some embodiments, a gas discharge conduit for guiding the gas may be connected to the air outlet hole 424.

[0065] In some alternative embodiments, the housing 420 may be integrally molded. In other alternative embodiments, the housing 420 may be formed by connecting multiple different components. For example, the housing 420 may include a first tank 426 having a top opening and a first tank cover 428 that closes the top opening of the first tank 426. The air inlet hole 423 is located on the first tank cover 428 and spaced apart from the air outlet hole 424. The first tank 426 has a straight pipe shape, and its pipe diameter is larger than the pipe diameter of the gas conduit. The top end of the first tank 426 is open and is sealed to the first tank cover 428. The bottom end of the first tank 426 is closed, and the liquid outlet hole 422 is provided thereon. There may be at least one liquid outlet hole 422.

[0066] The air inlet hole 423, together with the gas conduit and the air outlet hole 424, are covered by the first tank 426 to form a sleeve structure. The bottom end of the gas conduit is higher than the bottom end of the first tank 426, preventing gas flowing out of the gas conduit from leaking out of the first tank 426.

[0067] By providing the air inlet hole 423 and the air outlet hole 424 on the tank cover of the housing 420, the difficulty of drilling the holes is reduced, the manufacturing process is simplified, and the gas discharge efficiency is improved.

[0068] In some optional embodiments, the liquid storage container 200 may be molded as a single unit, which improves the sealing effect of the liquid storage container 200 and helps prevent leakage. In other optional embodiments, the liquid storage container 200 may be formed by connecting multiple different members. For example, the liquid storage container 200 may include a second tank 260 having a top opening and a second tank cover 280 that closes the top opening of the second tank 260. The second tank 260 may be a rectangular parallelepiped water tank without a lid, and its volume may be larger than the volume of the first tank 426.

[0069] Figure 6 is a schematic structural diagram of the second tank cover 280 of the liquid storage container 200 of the liquid storage device 20 shown in Figure 3. Figure 6(a) is a perspective view, Figure 6(b) is a front view, and Figure 6(c) is a top view.

[0070] An attachment port 282 is provided on the second tank cover 280. The hole wall of the attachment port 282 extends upward to form a hollow cylindrical male thread interface 288. Because the male thread interface 288 extends upward from the hole wall of the attachment port 282, the upper edge of the male thread interface 288 is higher than the upper surface of the second tank cover 280 and also higher than the upper edge of the liquid addition groove 286 described below. This allows the maximum liquid level during the liquid addition process to be controlled to be below the upper edge of the male thread interface 288.

[0071] The first tank cover 428 has a closing cover plate 428a above the first tank 426 and an annular female thread interface 428b extending downward from the outer edge of the closing cover plate 428a. Here, the closing cover plate 428a is used to cover the top opening of the first tank 426. The annular female thread interface 428b is threadedly connected to the male thread interface 288, and the first tank cover 428 is detachably connected to the second tank cover 280. That is, the annular female thread interface 428b is used to connect the first tank cover 428 to the second tank cover 280.

[0072] The first tank 426 extends downward from the underside of the closure cover plate 428 a and is inserted into the first liquid storage space 210 through the male threaded interface 288 .

[0073] The mounting opening 282 is closed using the threaded connection between the first tank cover 428 and the second tank cover 280, simplifying the process of mounting and fixing the filtration mechanism 400 and enabling one-step mounting in place, while at the same time allowing the first tank 426 to function as a "gas cutoff pipe."

[0074] 7 is a schematic diagram of the filtering and recovery process of the liquid storage device 20 shown in FIG. 1, where the arrows indicate the gas or liquid flow direction. Due to the limitations of the "gas cutoff pipe," the gas flowing out of the gas conduit can only rise in the form of bubbles inside the first tank 426 until it reaches the air outlet hole 424 in the first tank cover 428 above the first tank 426 and is discharged, thereby completing the filtering process. In some alternative embodiments, the above-mentioned screw and fastening installation methods may be replaced with methods such as interference fit or sealed connection using a seal ring, as long as watertightness and airtightness are guaranteed.

[0075] If the gas from the external environment contains soluble acidic or alkaline substances, these specific substance components are filtered out and remain in the first tank 426, and then gradually pass through the liquid outlet hole 422 at the bottom of the first tank 426 and diffuse into the liquid in the second tank 260. The first tank 426 may also function as a liquid replenishment tank, and the liquid therein can be transported again to the location where the reaction is occurring by liquid replenishment and reused.

[0076] In some alternative embodiments, a liquid addition port 284 may be provided on the second tank cover 280, with the wall of the port extending downward to form a liquid addition groove 286. The liquid addition groove 286 extends downward from the upper surface of the second tank cover 280, and the male thread interface 288 extends upward from the upper surface of the second tank cover 280. Therefore, when adding liquid to the second tank 260 through the liquid addition port 284, even if spillage of the second tank 260 occurs during the liquid addition process, the liquid level at the time of spillage will not exceed the male thread interface 288.

[0077] A portion of the groove wall of the liquid addition groove 286 extends at an angle downward, and a tapered opening is formed at the bottom of the liquid addition groove 286. In other words, the water tank is an angled through-hole with a constant depth, making it easy for the user to observe the liquid level when adding liquid. A liquid level mark is provided on the groove wall that extends at an angle downward and is used to indicate the liquid level during the liquid addition process. For example, the liquid level mark may be designed as a "maximum liquid level scale" to notify the user that the liquid is full.

[0078] A liquid supply port 262 is provided in the bottom zone of the liquid storage container 200 and is used to output the liquid to the external environment. The liquid supply port 262 is also provided in the bottom zone of the second tank 260. That is, the liquid storage container 200 can store the liquid and simultaneously transport the liquid to the external environment through the liquid supply port 262 for reuse, thereby optimizing the production process and improving production efficiency. For example, the liquid supply port 262 can be connected via a pipeline to an electrochemical deoxidation device that performs an electrochemical reaction, so that the electrochemical deoxidation device can be replenished with liquid, such as electrolyte or water.

[0079] A liquid supply port 262 is provided at the bottom zone of the second tank 260, so that the liquid in the second tank 260 can automatically flow out by gravity, which contributes to increasing the automation degree of the liquid supply process.

[0080] In some alternative embodiments, the edge of the second tank cover 280 has protrusions 287 that protrude outward to apply force, allowing the user to apply force to the second tank cover 280 by gripping it, thereby achieving the process of attaching and detaching the second tank cover 280 and the second tank 260.

[0081] An elastic sealing ring may be disposed around the periphery of the closed portion between the second tank cover 280 and the second tank 260. This allows the second tank cover 280 and the second tank 260 to be pressed together to achieve a tight seal, thereby preventing water leakage from the second tank 260.

[0082] 8 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 includes a reaction device 10. The refrigerator 1 generally includes a liquid storage device 20 according to any one of the above embodiments. The reaction device 10 may be an electrochemical deoxygenation device, which consumes oxygen inside the refrigerator 1 through an electrochemical reaction to reduce oxygen. In some alternative embodiments, the reaction device 10 may be replaced with other devices, such as a reaction device 10 for deodorization, according to actual needs.

[0083] The electrochemical deoxidation device includes a reaction vessel 500 that forms a location within which an electrochemical reaction takes place. Electrochemical reaction elements (anode plates, cathode plates, etc.) are disposed within the reaction vessel 500, and the reaction vessel 500 may store an electrolyte, such as a sodium hydroxide solution. The anode plates and cathode plates are each immersed in the electrolyte.

[0084] The cathode plate is in airflow communication with the interior space of the storage compartment of the refrigerator 1. When power is applied, the cathode plate consumes oxygen in the storage compartment through an electrochemical reaction. For example, oxygen in the air undergoes a reduction reaction at the cathode plate: O2 + 2H2O + 4e - →4OH - is.

[0085] The anode plate is disposed in the reaction vessel 500 at a distance from the cathode plate. When energized, the anode plate is used to supply reactants (e.g., electrons) to the cathode through an electrochemical reaction to produce oxygen. OH generated at the cathode plate is used to generate oxygen. - At the anode plate, oxidation occurs, producing oxygen. - →O2+2H2O+4e - The oxygen can be exhausted through an exhaust port 510 on the reaction vessel 500.

[0086] The filtering unit 440 is used to dissolve specific substance components in the gas from the electrochemical deoxidation device of the refrigerator 1 into the second liquid storage space 421. For example, the exhaust port 510 of the reaction vessel 500 communicates with the air inlet hole 423 of the housing 420, and oxygen generated in the reaction vessel 500 enters the gas conduit and is filtered, and the electrolyte carried by the oxygen remains in the second liquid storage space 421.

[0087] The first liquid storage space 210 is used to transport liquid to the electrochemical deoxygenation device of the refrigerator 1. For example, the reaction vessel 500 may be provided with a liquid refill port 520, and the liquid supply port 262 of the second tank 260 is connected to the liquid refill port 520 of the reaction vessel 500, so that the liquid in the first liquid storage space 210 flows sequentially through the liquid supply port 262 and the liquid refill port 520 and enters the reaction vessel 500. A liquid level switch 600 is installed in the reaction vessel 500 and is used to automatically open and close the liquid refill port 520 according to the liquid level in the reaction vessel 500.

[0088] In this embodiment, the liquid in the first liquid storage space 210 may be water or may be changed to an electrolyte solution because the electrochemical reaction of the electrochemical deoxygenation device consumes water. The liquid in the second liquid storage space 421 may be water or may be changed to an electrolyte solution because the electrolyte in the electrolyte solution carried by oxygen is water-soluble.

[0089] The organic cooperation between the liquid storage device 20 and the electrochemical deoxidation device allows the electrochemical deoxidation device to be automatically replenished with water, while at the same time removing the acidic or alkaline components in the exhaust gas generated by the electrochemical deoxidation device and recovering and reusing the electrolyte that would otherwise be lost. The entire process does not require the operation of specialized personnel or the use of electronic components, and the entire system has the advantages of integration, modularity and low cost.

[0090] Liquid storage device 20 has a filtering and recovery function and can output liquid to the external environment through liquid supply port 262. Therefore, when liquid storage device 20 is incorporated into the electrochemical deoxidation device of refrigerator 1, the gas discharged from the electrochemical deoxidation device is led to second liquid storage space 421, where specific substance components in the gas can be separated and reused. When the electrolyte in the electrochemical deoxidation device is insufficient, the liquid can be replenished using the liquid in first liquid storage space 210. Therefore, the refrigerator 1 of this embodiment can solve the problem of the difficulty in replenishing liquid during the deoxidation process and the loss of electrolyte.

[0091] In some alternative embodiments, the liquid reservoir 20 may cooperate with other reactors 10 and is not limited to the electrochemical deoxygenation devices of the above embodiments.

[0092] The liquid storage device 20 is separate from the reactor 10, thereby avoiding the risks of adding liquid directly to the reactor 10.

[0093] The interaction of the gas conduit and the housing 420 allows for gas filtration with water, avoiding the use of abrasive filter media and eliminating the need for filter media replacement, contributing to cost savings.

[0094] The design capacity of the liquid storage vessel 200 is capable of meeting the liquid replenishment needs of the reactor 10 within a set period of time.

[0095] 9 is a schematic structural diagram of a reaction system according to one embodiment of the present invention. The reaction system generally includes a reaction device 10 and a liquid storage device 20 according to any one of the above embodiments. The reaction system of this embodiment can realize the filtration and recovery / reuse of exhaust gas from the chemical reaction process.

[0096] As shown in Figure 9, the liquid supply port 262 of the liquid storage container 200 is connected to the liquid refill port 520 of the reaction container 500 via a liquid outlet pipe, and an infusion passage is formed between the first liquid storage space 210, the liquid supply port 262, the liquid refill port 520 and the internal space of the reaction container 500.

[0097] Since the liquid refill port 520 is lower than the liquid supply port 262 of the liquid storage container 200, the liquid in the first liquid storage space 210 flows downward by its own gravity to the liquid refill port 520. Since the liquid refill port 520 is located at the top of the reaction container 500, it prevents the reaction container 500 from leaking.

[0098] An exhaust port 510 is further provided at the top of the reaction vessel 500, and is connected to the second liquid storage space 421 through a gas pipe. One end of the gas pipe is connected to the exhaust port 510, and the other end is connected to the air inlet hole 423 of the housing 420.

[0099] FIG. 10 is a schematic structural diagram of a level switch 600 of a reaction system according to one embodiment of the present invention.

[0100] In some alternative embodiments, the reaction system further includes a level switch 600 having a switch body 620, which is disposed in the reaction vessel 500 and moves according to the liquid level in the reaction vessel 500 to open or close the liquid refill port 520, thereby allowing or preventing the liquid in the first liquid storage space 210 from entering the reaction vessel 500 through the liquid refill port 520. That is, the level switch 600 is used to control the opening and closing of the liquid refill port 520. That is, the level switch 600 serves as a gate of the infusion passage to open and close the infusion passage. The switch body 620 of the level switch 600 moves according to the liquid level in the reaction vessel 500 to open or close the liquid refill port 520, and the opening and closing process of the liquid refill port 520 does not need to be electronically controlled.

[0101] The liquid level switch 600 can automatically move according to the liquid level in the reaction vessel 500 to open and close the liquid refill port 520 and open and close the infusion passage, so that the reaction system of this embodiment has an automatic liquid refill function and can add liquid to the reaction vessel 500 from the external environment.

[0102] The switch body 620 is configured to be movable below the liquid refill port 520, and when the liquid level in the reaction vessel 500 rises, it rises and presses against the lower edge of the liquid refill port 520 to close the liquid refill port 520, and when the liquid level in the reaction vessel 500 falls, it descends and moves away from the lower edge of the liquid refill port 520 to open the liquid refill port 520.

[0103] That is, when the liquid level in the reaction vessel 500 rises, the switch body 620 rises and presses against the lower edge of the liquid refill port 520, closing the liquid refill port 520 and preventing the liquid in the first liquid storage space 210 from passing through the liquid refill port 520. When the liquid level in the reaction vessel 500 drops, the switch body 620 descends and separates to open the liquid refill port 520, allowing the liquid in the first liquid storage space 210 to flow downward into the reaction vessel 500 due to gravity.

[0104] The level switch 600 further includes a float 610, which is fixed to the switch body 620 by connection or is integrally molded with the switch body 620, and moves the switch body 620 by floating up or sinking within the reaction vessel 500. In other words, the switch body 620 is "driven" by the float 610, and the power required to move the float 610 is determined by the buoyant force experienced within the reaction vessel 500.

[0105] For example, when a portion of the float 610 is immersed in the liquid, the float 610 is subjected to the buoyancy of the liquid. When the liquid level in the internal space of the vessel changes, the buoyancy force applied to the float 610 also changes, and the resultant force of the buoyancy force and gravity applied to the float 610 changes. For example, when the liquid level in the reaction vessel 500 drops, the buoyancy force applied to the float 610 decreases, and if the direction of the resultant force of the buoyancy force and gravity applied to the float 610 is downward, the float 610 moves downward. Conversely, the float 610 moves upward. The float 610 may rise or fall along a vertical direction or along a curve.

[0106] In some alternative embodiments, the float 610 is configured to be rotatable around an axis. That is, the float 610 of this embodiment does not move up and down along a straight line, but rises and falls by rotating around an axis. With this design, the float 610 can be pivotally connected to a fixed axis, eliminating the need for a guide member with high dimensional accuracy, resulting in an ingenious structure, a simple assembly process, and good device reliability.

[0107] Since the float 610 is configured to be rotatable around an axis, its movement trajectory is clear, and the float 610 and the switch body 620 of this embodiment can easily move along a clear movement trajectory, improving the reliability of the level switch 600 and reducing or avoiding problems such as poor sealing caused by the free movement of the float 610.

[0108] The level switch 600 further includes a rotating shaft 630 and a connecting member 640 .

[0109] Here, the rotation shaft 630 is fixed to the reaction vessel 500. For example, the rotation shaft 630 may be fixed to the internal space of the reaction vessel 500 and fixed to the inner wall of the vessel of the reaction vessel 500 by connection.

[0110] In some optional embodiments, the rotating shaft 630 may be detachably fixed to the reaction vessel 500, and the height of the rotating shaft 630 can be adjusted according to actual needs to adjust the liquid level in the vessel at which liquid replenishment begins.

[0111] The connecting member 640 is fixed to the float 610 by connection or is integrally molded with the float 610, and has an axial hole formed thereon, into which the rotating shaft 630 is inserted and rotatably cooperates to realize a rotatable connection, that is, the connecting member 640 combines the rotating shaft 630 and the float 610 into an organic whole, and the float 610 can rotate around the rotating shaft 630.

[0112] An axial hole is provided on the connecting member 640, and the rotating shaft 630 is rotatably fitted into the axial hole, so that the float 610 is rotatably attached to the rotating shaft 630 around the axis, which is an ingenious structure and a simple process.

[0113] The switch body 620 is rod-shaped. An assembly port is further formed in the connecting member 640, and a portion of the switch body 620 is inserted therein to achieve assembly and fixation. That is, a portion of the switch body 620 is fixed by the connecting member 640 during assembly, and the fixation by connection with the float 610 can be indirectly achieved. For example, the portion of the switch body 620 may be assembled into the assembly port of the connecting member 640 by interference fit.

[0114] The rotation shaft 630 and the switch body 620 are respectively fixed to the float 610 by connection or assembled to a connecting member 640 molded integrally with the float 610, thereby forming the liquid level switch 600 and increasing the structural integrity.

[0115] In the liquid storage device 20 with filtration and recovery function of the present invention and the refrigerator 1 equipped therewith, the liquid storage device 20 has a filtering mechanism 400, and a second liquid storage space 421 communicating with the first liquid storage space 210 of the liquid storage container 200 is formed within the housing 420 of the filtering mechanism 400, and the filtering section 440 of the filtering mechanism 400 is used to dissolve specific substance components in gas in the external environment into the second liquid storage space 421 and allow the dissolved substance to flow into the first liquid storage space for reuse. Thus, the present invention provides a liquid storage device 20 with a filtration and recovery function, which can separate and reuse specific substance components in gas, thereby reducing or avoiding pollution caused by gas emissions and at the same time improving resource utilization efficiency.

[0116] In some embodiments, reactor 10 may be an electrolytic deoxidizer, and the reactor system comprising the electrolytic deoxidizer and liquid reservoir 20 is an electrolytic deoxidation system.

[0117] The present invention further provides an electrolytic deoxidation system for a refrigerator. Figure 11 is a schematic structural diagram of an electrolytic deoxidation system 2 for a refrigerator 1 according to one embodiment of the present invention. The electrolytic deoxidation system 2 generally includes an electrolytic deoxidation device 10 and a liquid storage device 20.

[0118] According to the embodiment of this embodiment, the electrolytic deoxidation device 10 and the liquid storage device 20 are organically combined to form the electrolytic deoxidation system 2, which can solve the problems of the difficulty of replenishing the liquid during the deoxidation process, the high safety risks, pollution caused by exhaust gas, electrolyte loss, etc., and ensure the continuous operation of the deoxidation process to a certain extent, promote the popularization and application of the electrolytic deoxidation device 10 in the field of refrigerators 1, and improve the freshness-preserving performance of the refrigerators 1.

[0119] The electrolytic deoxidation apparatus 10 has a reaction vessel 110, and a reaction site where oxygen is consumed through an electrochemical reaction is formed inside the reaction vessel 110 of the electrolytic deoxidation apparatus 10. The electrochemical reaction uses oxygen as a reactant and takes place inside the reaction vessel 110 of the electrolytic deoxidation apparatus 10. For example, an electrolyte may be contained inside the reaction vessel 110 of the electrolytic deoxidation apparatus 10, and the electrochemical element of the electrolytic deoxidation apparatus 10 may be immersed in the electrolyte to carry out the electrochemical reaction. The reaction vessel 110 is provided with a liquid refill port 116, which forms an opening that communicates between the interior and exterior spaces of the reaction vessel 110.

[0120] The liquid storage device 20 has a liquid storage container 200, inside which a liquid storage space (also referred to as a first liquid storage space) 210 is formed, and the liquid storage container 200 is provided with a liquid supply port 262 for communicating with the liquid refill port 116, which is used to refill the reaction container 110 with liquid. In other words, the liquid storage container 200 can serve as a liquid refill tank for the reaction container 110 and refill the reaction container 110 with liquid.

[0121] The electrolytic deoxidation system 2 is equipped with a liquid storage device 20 that replenishes liquid into the reaction vessel 110 of the electrolytic deoxidation apparatus 10. The electrolytic deoxidation system 2 of this embodiment integrates the deoxidation function and the liquid replenishment function, and can replenish liquid into the reaction vessel 110 using its own liquid storage device 20, which contributes to reducing the difficulty of replenishing liquid in the electrolytic deoxidation apparatus 10, makes the liquid replenishment process of the electrolytic deoxidation apparatus 10 safer, more effective, and more timely, and further ensures the deoxidation effect of the electrolytic deoxidation apparatus 10.

[0122] In some alternative embodiments, the liquid supply port 262 is located in the bottom zone of the liquid storage container 200. The liquid refill port 116 is located in the top zone of the reaction container 110. The liquid supply port 262 is higher than the liquid refill port 116. When the liquid supply port 262 and the liquid refill port 116 are respectively in an open state, a liquid infusion passage is formed between the liquid storage container 200 and the reaction container 110, and the liquid in the liquid storage container 200 flows sequentially through the liquid supply port 262 and the liquid refill port 116 into the reaction container 110 to complete the liquid refilling process.

[0123] The liquid supply port 262 of the liquid storage container 200 is higher than the liquid replenishment port 116 of the reaction container 110, so that the liquid from the liquid storage container 200 can enter the reaction container 110 by its own gravity, and the liquid replenishment process of the electrolytic deoxidation system 2 is performed automatically by a mechanical structure, which contributes to reducing electrical control costs and improving the degree of automation.

[0124] The electrolytic deoxidation system 2 further includes a liquid transport pipe 30 having one end communicating with the liquid supply port 262 and the other end communicating with the liquid replenishment port 116, and used to guide the liquid from the liquid supply port 262 to the liquid replenishment port 116.

[0125] The liquid transport pipe 30 connects the liquid supply port 262 and the liquid refill port 116, thereby ensuring smooth progress of the liquid refilling process and allowing the distance between the liquid storage device 20 and the electrolytic deoxidation device 10 to be appropriately increased, for example, allowing the liquid storage device 20 to be located in a place that is easily accessible, so that users or technicians can inspect or add liquid to the liquid storage container 200.

[0126] In this embodiment, the liquid in the liquid storage container 200 may be water or may be changed to an electrolyte solution because the electrochemical reaction in the electrolytic deoxidation device 10 consumes water. Because the electrolyte in the electrolyte solution carried by oxygen is water-soluble, the liquid in the housing 420 described below may also be water or may be changed to an electrolyte solution.

[0127] Fig. 12 is a schematic structural diagram of the electrolytic deoxidation apparatus 10 of the electrolytic deoxidation system 2 for a refrigerator 1 according to one embodiment of the present invention. Fig. 13 is a schematic exploded view of the electrolytic deoxidation apparatus 10 for the electrolytic deoxidation system 2 shown in Fig. 12. The electrolytic deoxidation apparatus 10 generally includes the above-mentioned reaction vessel 110, an anode plate 140, and a cathode plate 120. This embodiment is merely an example of the structure of the electrolytic deoxidation apparatus 10, and the structure of the electrolytic deoxidation apparatus 10 should not be considered to be limited thereto.

[0128] The reaction vessel 110 may be box-shaped. A side opening 114 may be provided on the reaction vessel 110.

[0129] The cathode plate 120 is disposed in the side opening 114 and defines a liquid storage chamber for containing an electrolyte together with the reaction vessel 110. The cathode plate 120 is configured to consume oxygen in the storage space 210 of the refrigerator 1 through an electrochemical reaction. The side opening 114 communicates with the storage space of the refrigerator 1, allowing the cathode plate 120 to be in airflow communication with the storage space. Oxygen in the air undergoes a reduction reaction at the cathode plate 120: O2 + 2H2O + 4e - →4OH - is.

[0130] For example, one wall of the reaction vessel 110 may be opened to form a side opening 114. The cathode plate 120 of this embodiment may be directly used as a side wall of the reaction vessel 110 to seal the liquid storage chamber. An alkaline electrolyte, for example, 1 mol / L NaOH, may be contained in the liquid storage chamber of the electrolytic deoxidation device 10, and its concentration may be adjusted according to actual needs.

[0131] The anode plate 140 is placed in the liquid reservoir and supplies reactants to the cathode plate 120 through an electrochemical reaction to produce oxygen. For example, OH generated at the cathode plate 120 - can undergo an oxidation reaction at the anode plate 140 to produce oxygen. - →O2+2H2O+4e - An anode power supply terminal 142 is formed on the anode plate 140. This terminal is used to connect to an external power source.

[0132] An exhaust port 112 is further provided on the reaction vessel 110, allowing gas generated in the reaction vessel 110 to be discharged into the interior space of the housing described below. In this embodiment, the anode plate 140 generates oxygen during an electrochemical reaction, and the exhaust port allows the oxygen generated by the anode plate 140 to be discharged. The exhaust port 112 may be provided near the top of the reaction vessel 110, which can reduce or prevent leakage of the electrolyte. In some embodiments, an exhaust pipe 160 is connected to the exhaust port 112, and the exhaust pipe communicates with the gas delivery pipe 40.

[0133] In some embodiments, the electrolytic deoxidation apparatus 10 may further include a separation member 130 and a fixing assembly 150. Here, the separation member 130 is disposed in the liquid storage chamber and positioned between the cathode plate 120 and the anode plate 140, and is used to separate the cathode plate 120 and the anode plate 140 and prevent short-circuiting of the electrolytic deoxidation apparatus 10. Specifically, a plurality of protrusions 132 are formed on the side of the separation member 130 facing the anode plate 140, and the protrusions 132 abut against the anode plate 140. The cathode plate 120 is attached to the side of the separation member 130 away from the protrusions 132, thereby forming a predetermined gap between the cathode plate 120 and the anode plate 140 and further separating the cathode plate 120 and the anode plate 140.

[0134] The fixing assembly 150 is disposed outside the cathode plate 120 and is configured to fix the cathode plate 120 to the side opening 114 of the reaction vessel 110. Specifically, the fixing assembly 150 includes a metal frame 152 and a support member 154. The metal frame 152 is attached to the outside of the cathode plate 120. The metal frame 152 is in direct contact with the cathode plate 120 and serves to press the cathode plate 120. The metal frame 152 is provided with a cathode power supply terminal 152b of the cathode plate 120 for connection to an external power source. An insertion groove is formed in the support member 154. When the surrounding portion 152a of the metal frame 152 enters the insertion groove of the support member 154, the metal frame 152 is fixed and positioned by the support member 154, and the metal frame 152 presses the cathode plate 120.

[0135] In some embodiments, the electrolytic deoxidation system 2 further includes a filtration mechanism 400 having a housing 420 and a filtration unit 440. As shown in FIGS. 4 and 5 , the filtration mechanism 400 has an internal space (also referred to as a second liquid storage space) 421 of the housing 420 that is connected to the liquid storage space 210. The filtration unit 440 is disposed in the internal space 421 of the housing 420, allowing specific substance components in the gas from the exhaust port 112 to dissolve in the internal space 421 of the housing 420 and flow into the liquid storage space 210 for reuse. That is, the gas discharged from the exhaust port 112 is filtered by the filtration unit 440, and the specific substance components are separated and remain in the internal space 421 of the housing 420. A space for containing a liquid, such as an electrolyte solution or water containing the specific substance, is formed within the housing 420. Dissolving the specific substance components in the gas discharged from the reaction vessel 110 in the internal space 421 of the housing 420 refers to dissolving the specific substance components in the liquid contained in the reaction vessel 110.

[0136] The filtering mechanism 400 can dissolve specific substance components in the gas discharged from the electrolytic deoxidation device 10 into the internal space 421 of the housing 420, thereby filtering the gas to be discharged, reducing the corrosiveness of the gas discharged from the electrolytic deoxidation device 10, and contributing to reducing the adverse impact of the deoxidation process on the environment.

[0137] Furthermore, since the housing 420 of the filtering mechanism 400 is connected to the liquid storage space 210, specific substance components dissolved in the housing 420 can enter the liquid storage space 210, and therefore specific substance components in the gas discharged from the electrolytic deoxidation device 10 can be recovered and reused, which contributes to reducing resource consumption in the deoxidation process.

[0138] The specific substance components may be water-soluble. In some alternative embodiments, the liquid composition stored in the housing 420 and the liquid storage vessel 200 may be adjusted depending on the physicochemical properties of the specific substance components to be separated.

[0139] 1 to 3, regarding the communication method between the housing 420 and the liquid storage space 210, in some alternative embodiments, the housing 420 is inserted into the liquid storage space 210, and a liquid outlet hole communicating with the liquid storage space 210 is provided at the bottom of the housing 420, allowing the liquid in the housing 420 to flow back into the liquid storage container 200. For example, the liquid storage container 200 may be substantially rectangular parallelepiped-shaped, and the housing 420 may be inserted into the liquid storage container 200 as an inner sleeve. Examples of the shapes of the liquid storage container 200 and the housing 420 are merely illustrative and will be readily apparent to those skilled in the art, and are not all listed herein.

[0140] The liquid outlet hole 422 can function as a "window" for material exchange between the internal space 421 of the housing 420 and the internal space of the liquid storage container 200 (i.e., the liquid storage space 210). The liquid outlet hole 422 makes the liquid levels of the internal space 421 of the housing 420 and the internal space of the liquid storage container 200 equal, making it easier for the liquid in the housing 420 to diffuse into the liquid storage container 200.

[0141] A housing 420 is provided in the internal space of the liquid storage container 200 and communicates with the liquid storage container 200 through a liquid outlet hole 422 at the bottom of the housing 420, allowing the liquid in the housing 420 to flow downward through the liquid outlet hole 422 and back into the liquid storage container 200 due to its own gravity, thereby making the recovery process easy and effective.

[0142] An air inlet hole 423 is provided on the housing 420 to communicate between the exhaust port 112 and an internal space 421 of the housing 420. The electrolytic deoxidation system 2 further includes a gas transport pipe 40 having one end communicating with the exhaust port 112 and the other end communicating with the air inlet hole 423, and used to guide gas from the exhaust port 112 to the air inlet hole 423.

[0143] By connecting the exhaust port 112 and the air inlet hole 423 via the gas transport pipe 40, the connection structure of the gas transport pipeline between the exhaust port 112 and the air inlet hole 423 can be simplified, and the flexibility of the assembly process can be improved.

[0144] In some alternative embodiments, the filtering section 440 is a gas conduit, which is inserted into the interior space 421 of the housing 420 through the air inlet hole 423 and extends to the bottom zone within the housing 420, directing the gas from the exhaust port 112 to the bottom zone within the housing 420 and dissolving specific substance components in the gas from the exhaust port 112 into the interior space 421 of the housing 420 during the upward flow. The gas conduit in this embodiment may be a straight pipe, with both ends open, which facilitates the introduction and release of gas, has a simple structure, and has excellent gas conduction effect.

[0145] By extending the gas conduit to the bottom zone within the housing 420, the gas conduit can transport the gas deep into the liquid within the housing 420, lengthening the gas flow path within the housing 420. The gas flowing out of the gas conduit comes into sufficient contact with the liquid within the housing 420 as it rises, dissolving specific substance components in the gas within the housing 420. This allows the electrolytic deoxidation system 2 to achieve excellent filtering, purification, and recovery effects despite its clever and simple structure.

[0146] In some alternative embodiments, the shape of the gas conduit may be modified into a vertical curved hook-shaped tube, with a straight section extending to the bottom zone of the housing 420 and a curved section extending upward from the end of the straight section. The end of the curved section is slightly higher than the end of the straight section and is used to guide the gas flowing through it upward. The straight section resembles an umbrella pole, and the curved section resembles an umbrella handle connected to the end of the umbrella pole. The curved section extends upward from the end of the straight section, and guides the gas flowing out of the gas conduit to flow upward, making the direction of gas movement clearer. The fact that the end of the curved section is slightly higher than the end of the straight section does not significantly shorten the gas flow path during the dissolution process, as the end of the curved section is still located in the bottom zone of the housing 420.

[0147] The housing 420 is further provided with an air outlet hole 424, which is located at the top of the housing 420 and spaced apart from the air inlet hole 423, and is used to discharge the gas from which the specific substance components have been separated that flows through the gas conduit and the internal space of the housing 420. The air outlet hole 424 is used to discharge the filtered gas to the external environment, for example, the air in the external environment.

[0148] In some embodiments, the air inlet hole 423 and the air outlet hole 424 are each provided on the top cover of the housing 420 (i.e., the first tank cover 428 described below). The air inlet hole 423 and the air outlet hole 424 are each circular openings. In this embodiment, the air inlet hole 423 and the air outlet hole 424 are each tubular through-holes. The gas conduit and the air inlet hole 423 may be integrally molded. The hole wall of the tubular hole of the air inlet hole 423 extends continuously downward into the housing and functions as a gas conduit. In some embodiments, a gas discharge conduit for guiding gas may be attached to the air outlet hole 424.

[0149] In some alternative embodiments, the housing 420 may be integrally molded. In other alternative embodiments, the housing 420 may be formed by connecting multiple different components. For example, the housing 420 includes a first tank 426 having a top opening and a first tank cover 428 that closes the top opening of the first tank 426. The air inlet hole 423 and the air outlet hole 424 are spaced apart from each other and located in the first tank cover 428. The first tank 426 may be a straight pipe, and its diameter is larger than that of the gas conduit. The top end of the first tank 426 is open and is sealed to the first tank cover 428. The bottom end of the first tank 426 is closed, and the liquid outlet hole 422 is provided thereon. There is at least one liquid outlet hole 422.

[0150] The air inlet hole 423, together with the gas conduit and the air outlet hole 424, are covered by the first tank 426 to form a sleeve structure. The bottom end of the gas conduit is higher than the bottom end of the first tank 426, preventing gas flowing out of the gas conduit from leaking into the first tank 426.

[0151] In some optional embodiments, the liquid storage container 200 may be molded as a single unit, which improves the sealing effect of the liquid storage container 200 and helps prevent leakage. In other optional embodiments, the liquid storage container 200 is formed by connecting multiple different members. For example, the liquid storage container 200 includes a second tank 260 having a top opening and a second tank cover 280 that closes the top opening of the second tank 260. The second tank 260 may be a rectangular parallelepiped water tank without a lid, and its volume may be larger than the volume of the first tank 426.

[0152] 6, the second tank cover 280 is provided with an access hole 282. The hole wall of the access hole 282 extends upward to form a hollow cylindrical male thread interface 288. Because the male thread interface 288 extends upward from the hole wall of the access hole 282, the upper edge of the male thread interface 288 is higher than the upper surface of the second tank cover 280 and is also higher than the upper edge of the liquid addition groove 286 described below. This allows the maximum liquid level during the liquid addition process to be controlled to be below the upper edge of the male thread interface 288.

[0153] The first tank cover 428 has a closing cover plate 428a above the first tank 426 and an annular female thread interface 428b extending downward from the outer edge of the closing cover plate 428a. Here, the closing cover plate 428a is used to cover the top opening of the first tank 426. The annular female thread interface 428b is threadably connected to the male thread interface 288, and the first tank cover 428 is detachably connected to the second tank cover 280. That is, the annular female thread interface 428b is used to connect the first tank cover 428 to the second tank cover 280.

[0154] The first tank 426 extends downwardly from the underside of the closure cover plate 428 a and is inserted into the liquid storage container 200 through the male threaded interface 288 .

[0155] By using the threaded connection between the first tank cover 428 and the second tank cover 280 to close the mounting port 282, the process of mounting and fixing the filtration mechanism 400 can be simplified, allowing it to be mounted in place in one step, and at the same time the first tank 426 functions as a "gas cutoff pipe."

[0156] The filtering and recovery process of the electrolytic deoxidation system 2 for the refrigerator 1 of this embodiment is similar to that of the liquid storage device 20, as shown in FIG. 7. The arrows in the figure indicate the direction of gas or liquid flow. Due to the restriction of the housing 420 as a "gas cutoff pipe," the gas flowing out of the gas conduit can only rise in the form of bubbles inside the first tank 426 until it reaches the air outlet hole 424 in the first tank cover 428 above the first tank 426 and is discharged, completing the filtering process. In some alternative embodiments, the above-mentioned screw and fastening installation methods may be replaced with methods such as an interference fit or a sealed connection using a seal ring, as long as watertightness and airtightness are guaranteed.

[0157] If the gas discharged from the exhaust port 112 contains soluble acidic or alkaline substances, these specific substance components are filtered out and remain in the first tank 426, and then gradually pass through the liquid outlet hole 422 at the bottom of the first tank 426 and diffuse into the liquid in the second tank 260. The first tank 426 functions as a liquid replenishment tank, and the liquid therein can be transported back to the reaction vessel 110 by liquid replenishment, thereby realizing reuse.

[0158] In some alternative embodiments, the second tank cover 280 is provided with a liquid addition port 284, the wall of which extends downward to form a liquid addition groove 286. The liquid addition groove 286 extends downward from the upper surface of the second tank cover 280, and the male thread interface 288 extends upward from the upper surface of the second tank cover 280. Therefore, when liquid is added to the second tank 260 through the liquid addition port 284, even if the second tank 260 spills during the liquid addition process, the liquid level at the time of spillage will not exceed the male thread interface 288.

[0159] A portion of the groove wall of the liquid addition groove 286 extends downward at an angle, and a tapered opening is formed at the bottom of the liquid addition groove 286. In other words, the water addition tank is a sloped through-hole with a constant depth, making it easy for the user to observe the liquid level when adding liquid. A liquid level mark is provided on the groove wall that extends downward at an angle and is used to indicate the liquid level during the liquid addition process. For example, the liquid level mark may be designed as a "maximum liquid level scale" to notify the user that the liquid is full.

[0160] A liquid supply port 262 is provided at the bottom zone of the second tank 260, so that the liquid in the second tank 260 can be automatically discharged by gravity, which contributes to improving the automation degree of the liquid supply process.

[0161] In some alternative embodiments, the second tank cover 280 has a protrusion 287 on the edge thereof that protrudes outward for applying force. A user can apply force to the second tank cover 280 by gripping it, thereby realizing the process of attaching or detaching the second tank cover 280 and the second tank 260.

[0162] An elastic sealing ring may be provided around the periphery of the closed portion between the second tank cover 280 and the second tank 260, and the second tank cover 280 and the second tank 260 are pressed together to achieve a tight seal, thereby preventing water leakage from the second tank 260.

[0163] FIG. 14 is a schematic block diagram of a refrigerator 1 according to another embodiment of the present invention. The refrigerator 1 generally includes the electrolytic deoxidation system 2 according to any one of the above embodiments and further includes a cabinet. A storage space is formed inside the cabinet. An electrolytic deoxidation device 10 is in airflow communication with the storage space, and the electrolytic deoxidation device 10 consumes oxygen in the storage space through an electrochemical reaction. A cathode plate 120 of the electrolytic deoxidation device 10 is in airflow communication with the storage space. For example, the cathode plate may be disposed facing the storage space, or the cathode plate may be connected to the storage space via a connecting pipeline.

[0164] The organic cooperation between the liquid storage device 20 and the electrolytic deoxidation device 10 allows the electrolytic deoxidation device 10 to be automatically replenished with water, and at the same time, the acidic or alkaline components in the exhaust gas generated by the electrolytic deoxidation device 10 can be removed, and the electrolyte lost in the main body can be recovered and reused. The entire process does not require specialized personnel to operate, and no electronic components are required, and the entire system has the advantages of integration, modularity, and low cost.

[0165] The liquid storage device 20 is independent of the reactor 10, thereby avoiding the risk of adding liquid directly to the reactor 10. The design capacity of the liquid storage container 200 can meet the liquid replenishment demand of the reactor 10 within a set time. The interaction between the gas conduit and the housing 420 realizes gas filtration by water, avoiding the use of abrasive filter media and eliminating the need for filter media replacement, contributing to cost savings.

[0166] In some alternative embodiments, as shown in FIG. 10 , the electrolytic deoxidation system 2 may further include a liquid level switch 600. The liquid level switch 600 is disposed in the reaction vessel 110 and has a switch body 620. The switch body 620 moves in response to the liquid level in the reaction vessel 110 to open or close the liquid refill port 116, thereby allowing or preventing the liquid in the liquid storage container 200 from flowing through the liquid supply port 262 and the liquid refill port 116 into the reaction vessel 110. That is, the liquid level switch 600 controls the opening and closing of the liquid refill port 116. That is, the liquid level switch 600 serves as a gate for the infusion passage, opening and closing the infusion passage. The switch body 620 of the liquid level switch 600 moves in response to the liquid level in the reaction vessel 110 to open or close the liquid refill port 116, and the opening and closing process of the liquid refill port 116 does not need to be electronically controlled.

[0167] The liquid level switch 600 can automatically move according to the liquid level in the reaction vessel 110 to open and close the liquid refill port 116 and the infusion passage, so that the electrolytic deoxidation system 2 of this embodiment has an automatic liquid refill function and can add liquid to the reaction vessel 110 from the external environment.

[0168] The switch body 620 is configured to be movable below the liquid refill port 116, and when the liquid level in the reaction vessel 110 rises, it rises and presses against the lower peripheral edge of the liquid refill port 116, closing the liquid refill port 116, and when the liquid level in the reaction vessel 110 falls, it descends and moves away from the lower peripheral edge of the liquid refill port 116, opening the liquid refill port 116.

[0169] That is, when the liquid level in the reaction vessel 110 rises, the switch body 620 rises and presses against the lower edge of the liquid refill port 116, closing the liquid refill port 116, preventing the liquid in the liquid storage vessel from passing through the liquid refill port 116; when the liquid level in the reaction vessel 110 drops, the switch body 620 descends and separates to open the liquid refill port 116, allowing the liquid in the liquid storage vessel to flow downward into the reaction vessel 110 due to gravity.

[0170] The level switch 600 further includes a float 610, which is fixed to the switch body 620 by connection or is integrally molded with the switch body 620 and moves the switch body 620 by floating or sinking within the reaction vessel 110. In other words, the switch body 620 is "driven" by the float 610, and the power required to move the float 610 is determined by the buoyant force experienced within the reaction vessel 110.

[0171] For example, when a portion of the float 610 is immersed in the liquid, the float 610 is subjected to the buoyancy of the liquid. When the liquid level in the internal space of the reaction vessel 110 changes, the buoyancy force applied to the float 610 also changes, and the resultant force of the buoyancy and gravity applied to the float 610 changes. For example, when the liquid level in the reaction vessel 110 drops, the buoyancy force applied to the float 610 decreases, and if the direction of the resultant force of the buoyancy and gravity applied to the float 610 is downward, the float 610 will move downward. Conversely, the float 610 will move upward.

[0172] In this embodiment, the float 610 does not move up and down in a straight line, but rises or falls by rotating around an axis. With this design, the float 610 is only pivotally connected to a fixed axis, eliminating the need for a guide member with high dimensional accuracy, resulting in an ingenious structure, a simple assembly process, and good device reliability.

[0173] Since the float 610 is configured to be rotatable around an axis, its movement trajectory is clear, and the float 610 and the switch body 620 of this embodiment can easily move along a clear movement trajectory, improving the reliability of the level switch 600 and reducing or avoiding problems such as poor sealing caused by the free movement of the float 610.

[0174] The level switch 600 further includes a rotating shaft 630 and a connecting member 640 .

[0175] Here, the rotation shaft 630 is fixed to the reaction vessel 110. For example, the rotation shaft 630 may be fixed to the internal space of the reaction vessel 110 and fixed to the inner wall of the vessel of the reaction vessel 110 by a connection.

[0176] In some optional embodiments, the rotating shaft 630 may be detachably fixed to the reaction vessel 110, and the height of the rotating shaft 630 can be adjusted according to actual needs to adjust the liquid level in the vessel at which liquid replenishment begins.

[0177] The connecting member 640 is fixed to the float 610 by connection or is integrally molded with the float 610, and has an axial hole formed thereon, into which the rotating shaft 630 is inserted and rotatably cooperates to realize a rotatable connection, that is, the connecting member 640 combines the rotating shaft 630 and the float 610 into an organic whole, and the float 610 can rotate around the rotating shaft 630.

[0178] An axial hole is provided on the connecting member 640, and the rotating shaft 630 is rotatably disposed in the axial hole, so that the float 610 is rotatably attached to the rotating shaft 630 around its axis, which has an ingenious structure and a simple process.

[0179] The switch body 620 is rod-shaped. An assembly port is further formed in the connecting member 640, and a portion of the switch body 620 is inserted therein to achieve assembly and fixation. That is, a portion of the switch body 620 is fixed by the connecting member 640 during assembly, and the fixation by connection with the float 610 can be indirectly achieved. For example, the portion of the switch body 620 may be assembled into the assembly port of the connecting member 640 by interference fit.

[0180] The rotation shaft 630 and the switch body 620 are respectively fixed to the float 610 by connection or assembled to a connecting member 640 molded integrally with the float 610, thereby forming the liquid level switch 600 and increasing the structural integrity.

[0181] In the electrolytic deoxidation system 2 for refrigerator 1 and the refrigerator 1 equipped with the same of this embodiment, the electrolytic deoxidation system 2 has a liquid storage device 20 for refilling liquid into the reaction vessel 110 of the electrolytic deoxidation apparatus 10. Therefore, the electrolytic deoxidation system 2 of the present invention integrates the deoxidation function and the liquid refilling function and uses its own liquid storage device 20 to refill the reaction vessel 110 with liquid, which contributes to reducing the difficulty of refilling liquid into the electrolytic deoxidation apparatus 10. The liquid refilling process of the electrolytic deoxidation apparatus 10 is safer, more effective, more timely, and more intelligent, and the deoxidation effect of the electrolytic deoxidation apparatus 10 can be further ensured.

[0182] Although several illustrative embodiments of the present invention have been shown and described herein, it should be understood by those skilled in the art that many other variations or modifications that conform to the principles of the present invention can be directly determined or inferred based on the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering such other variations or modifications.
