Description

Technical Field

[0001] This invention relates to preservation technology, and in particular to an electrolytic deoxygenation device and a refrigerator having the same. Background Technology

[0002] For some reaction devices, such as electrolytic deoxygenation devices used to reduce oxygen levels inside a refrigerator through electrochemical reactions, the electrochemical reaction process requires the participation of an electrolyte, and the reaction process produces gas, which needs to be released into the external environment.

[0003] During the reaction, a large amount of heat is generated, causing the electrolyte to evaporate. This can result in trace amounts of electrolyte vapor being carried in the gas emitted from the reaction vessel. Most electrolytes are acidic or alkaline solutions and are corrosive. If the gas produced by the reaction vessel is released directly into the air without treatment, it can lead to air pollution and endanger human health. Summary of the Invention

[0005] A further objective of this invention is to enable the electrolytic deoxygenation device to have a filtration function, thereby reducing or avoiding environmental pollution caused by gas emissions.

[0006] Another further objective of the present invention is to improve the resource utilization efficiency of the electrolytic deoxygenation device.

[0007] Another further objective of the present invention is to simplify the structure of the electrolytic oxygenation device and improve its structural integrity.

[0008] Another further objective of this invention is to improve the gas emission efficiency of each reaction space and avoid excessive impact of gas on the various components of the electrolytic oxygenation unit.

[0009] Another further objective of the present invention is to improve the deoxygenation efficiency of the electrolytic deoxygenation device while ensuring its service life.

[0010] According to one aspect of the present invention, an electrolytic deoxygenation device is provided, comprising: at least one electrolytic deoxygenation unit for consuming oxygen outside the electrolytic deoxygenation device through an electrochemical reaction under the action of an electrolytic voltage; and a reaction vessel defining a liquid-sealed space and at least one reaction space therein; an electrolytic deoxygenation unit is correspondingly assembled in a reaction space; the liquid-sealed space is used to hold liquid and is connected to the reaction space by a gas path, so that the gas generated when the electrolytic deoxygenation unit performs an electrochemical reaction flows through the liquid held in the liquid-sealed space, thereby dissolving a specific substance component in the gas into the liquid-sealed space.

[0011] Optionally, the reaction vessel has a transverse partition plate that extends laterally to separate a liquid-sealed space and a reaction space arranged vertically; and the transverse partition plate has at least one exhaust port, with each exhaust port corresponding to a reaction space, so that the liquid-sealed space and the reaction space are connected by gas path.

[0012] Optionally, at least one liquid inlet is provided on the transverse partition plate, with each liquid inlet corresponding to a reaction space, so that the liquid seal space and the reaction space are connected by liquid path; and the liquid inlet is set higher than the exhaust port.

[0013] Optionally, the liquid inlet and the vent are hollow cylindrical nozzles that penetrate the transverse partition and extend into the liquid seal space.

[0014] Optionally, an outlet is provided on the top wall of the liquid-sealed space to connect with the liquid-sealed space, so as to allow the filtered gas to be discharged.

[0015] Optionally, the electrolytic deoxygenation device further includes: a replenishment container located above the reaction vessel, and having an internal liquid storage space connected to the liquid seal space for replenishing the liquid seal space.

[0016] Optionally, there are multiple electrolytic deoxygenation units and multiple reaction spaces; and the multiple reaction spaces are not interconnected and are arranged sequentially along the horizontal direction.

[0017] Optionally, the reaction vessel has at least one longitudinal partition plate, which extends longitudinally to separate multiple reaction spaces arranged sequentially in the horizontal direction.

[0018] Optionally, the electrolytic oxygen removal unit includes: a cathode plate for consuming oxygen through an electrochemical reaction under the action of an electrolysis voltage, and having a cathode terminal; and an anode plate for providing reactants to the cathode plate and generating gas through an electrochemical reaction under the action of an electrolysis voltage, and having an anode terminal; and the cathode terminals of adjacent electrolytic oxygen removal units are connected to the anode terminals.

[0019] According to another aspect of the present invention, a refrigerator is also provided, comprising: an electrolytic deoxygenation device as described in any of the above claims.

[0020] The electrolytic deoxygenation device and refrigerator of the present invention, since the interior of the reaction vessel defines a liquid-sealed space and a reaction space, the electrolytic deoxygenation unit is assembled into the reaction space, and the gas generated when the electrolytic deoxygenation unit performs an electrochemical reaction can flow through the liquid contained in the liquid-sealed space, so that specific substances in the gas dissolve in the liquid-sealed space. Therefore, the present invention provides an electrolytic deoxygenation device with a filtration function, which is beneficial to reduce or avoid environmental pollution caused by gas emissions.

[0021] Furthermore, in the electrolytic deoxygenation device and refrigerator of the present invention, since the liquid seal space and the reaction space are connected by a liquid replenishment port, specific substances dissolved in the liquid seal space can be returned to the reaction space through the liquid replenishment port for recycling and reuse, which is beneficial to improving the resource utilization efficiency of the electrolytic deoxygenation device.

[0022] Furthermore, in the electrolytic deoxygenation device and refrigerator of the present invention, since the reaction space and liquid seal space are both integrated in the reaction vessel, the gas path and liquid path can be connected between the reaction space and the liquid seal space by opening an opening on the transverse partition plate, thereby realizing the filtration function and the recovery function. Therefore, the electrolytic deoxygenation device of the present invention has the advantages of simple structure and high degree of integration.

[0023] Furthermore, in the electrolytic deoxygenation device and the refrigerator having it of the present invention, since each reaction space is not interconnected, it is equivalent to each reaction space being set independently and not interfering with each other. Therefore, the gas generated in each reaction space can only be discharged to the liquid-sealed space through the exhaust port. This can prevent the gas generated in each reaction space from entering other reaction spaces, which is beneficial to improving the gas emission efficiency of each reaction space and avoiding excessive impact of gas on the various components of the electrolytic deoxygenation unit.

[0024] Furthermore, the electrolytic deoxygenation device and the refrigerator having the present invention, having multiple electrolytic deoxygenation units, each of which can consume oxygen through an electrochemical reaction under the action of an electrolysis voltage, allows each unit to operate at a relatively low electrolysis voltage while simultaneously performing an electrochemical reaction, thus achieving high deoxygenation efficiency. Therefore, the electrolytic deoxygenation device of the present invention improves deoxygenation efficiency while ensuring service life.

[0025] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

In the drawings:

[0029] Figure 3 This is a schematic structural diagram of an electrolytic deoxygenation device according to another embodiment of the present invention;

[0030] Figure 4 This is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. Detailed Implementation

[0031] Figure 1 This is a schematic structural diagram of an electrolytic oxygen desorption device 10 according to an embodiment of the present invention. The electrolytic oxygen desorption device 10 of this embodiment is used to be installed in a refrigerator 1 to consume oxygen in the storage space of the refrigerator 1.

[0032] The electrolytic deoxygenation apparatus 10 generally includes a reaction vessel 200 and at least one electrolytic deoxygenation unit 100.

[0033] The reaction vessel 200 internally defines a liquid-sealed space 230 and at least one reaction space 220. Each reaction space 220 is equipped with an electrolytic deoxygenation unit 100. In this embodiment, the number of reaction spaces 220 is the same as the number of electrolytic deoxygenation units 100, and they are arranged in a one-to-one correspondence. Each reaction space 220 is equipped with one electrolytic deoxygenation unit 100.

[0034] The liquid-sealed space 230 is used to hold liquid and is connected to the gas path of the reaction space 220. This allows the gas generated during the electrochemical reaction in the electrolytic deoxygenation unit 100 to flow through the liquid contained in the liquid-sealed space 230, thereby dissolving specific components in the gas within the liquid-sealed space 230. In other words, the gas discharged from the reaction space 220 is filtered as it flows through the liquid-sealed space 230, thus purifying the gas. The specific components may refer to the electrolyte in the electrolyte carried by the gas.

[0035] Since the interior of the reaction vessel 200 defines a liquid-sealed space 230 and a reaction space 220, the electrolytic deoxygenation unit 100 is assembled into the reaction space 220. The gas generated during the electrochemical reaction of the electrolytic deoxygenation unit 100 can flow through the liquid contained in the liquid-sealed space 230, causing specific components in the gas to dissolve in the liquid-sealed space 230. Therefore, the present invention provides an electrolytic deoxygenation device 10 with a filtration function, which is beneficial to reduce or avoid environmental pollution caused by gas emissions.

[0036] In this embodiment, the liquid contained in the liquid-sealed space 230 can be water. In some optional embodiments, the liquid contained in the liquid-sealed space 230 can also be replaced with other solvents, such as a low-concentration NaOH aqueous solution, depending on the solubility of the electrolyte carried by the gas.

[0037] By integrating a liquid-sealed space 230 and a reaction space 220 within the reaction vessel 200, the gas generated in the reaction space 220 flows through the liquid contained in the liquid-sealed space 230, thus purifying the gas generated in the reaction space 220. This purification method is ingenious and provides excellent filtration. Furthermore, there is no need to install a purification mechanism externally on the electrolytic oxygen desorption device 10. The electrolytic oxygen desorption device 10 of this embodiment has the advantages of compact structure and high degree of integration.

[0038] In some optional embodiments, the reaction vessel 200 has a transverse partition 250 extending laterally to separate a liquid-sealed space 230 and a reaction space 220 arranged vertically. That is, the liquid-sealed space 230 is located above the reaction space 220. For example, the transverse partition 250 may be flat or sheet-like, and its surface may be parallel to the horizontal plane.

[0039] At least one exhaust port 251 is provided on the transverse partition plate 250, and each exhaust port 251 is connected to a corresponding reaction space 220, thus connecting the liquid-sealed space 230 and the reaction space 220 in terms of gas path. Gas generated in each reaction space 220 can flow into the liquid-sealed space 230 through the corresponding exhaust port 251. The number of exhaust ports 251 is the same as the number of reaction spaces 220, and they are arranged in a one-to-one correspondence, ensuring that gas generated in each reaction space 220 can flow into the liquid-sealed space 230 for filtration.

[0040] In this embodiment, the electrolytic deoxygenation device 10 can connect the reaction space 220 and the liquid-sealed space 230 by opening an exhaust port 251 on the transverse partition plate 250. The gas generated in the reaction space 220 can flow into the liquid-sealed space 230 for filtration by relying on its own upward movement. No other guiding mechanism needs to be installed, which has the advantages of simple and ingenious structure.

[0041] In some embodiments, the transverse partition 250 can be formed inside the reaction vessel 200 by injection molding, which simplifies the process, eliminates the complicated assembly process, and ensures the connectivity between the reaction space 220 and the liquid seal space 230.

[0042] The exhaust rate of exhaust port 251 is greater than the maximum gas generation rate of electrolytic deoxygenation unit 100, so as to prevent the impact of large gas pressure in reaction space 220 on the various components of electrolytic deoxygenation unit 100.

[0043] In some further embodiments, the transverse partition 250 is also provided with at least one liquid replenishment port 252, each liquid replenishment port 252 corresponding to a reaction space 220, thereby connecting the liquid-sealed space 230 and the reaction space 220 in a liquid path. Liquid contained in the liquid-sealed space 230 can flow into the reaction space 220 through the liquid replenishment port 252, thus replenishing the reaction space 220. The number of liquid replenishment ports 252 is the same as the number of reaction spaces 220, and they are arranged in a one-to-one correspondence, so that each reaction space 220 can receive liquid from the liquid-sealed space 230.

[0044] Since the liquid seal space 230 and the reaction space 220 are connected by the liquid replenishment port 252, specific substances dissolved in the liquid seal space 230 can be returned to the reaction space 220 through the liquid replenishment port 252 for recycling and reuse. This is beneficial to improving the resource utilization efficiency of the electrolytic deoxygenation device 10.

[0045] The replenishment port 252 is positioned higher than the exhaust port 251, so that the liquid contained in the liquid-sealed space 230 can seal the exhaust port 251. In other words, when the liquid in the liquid-sealed space 230 can enter the reaction space 220 through the replenishment port 252, the liquid level in the liquid-sealed space 230 is higher than the exhaust port 251, thereby sealing the exhaust port 251.

[0046] The liquid seal vent 251 in the liquid seal space 230 ensures that all gas flowing out of the vent 251 flows through the liquid seal space 230, preventing unfiltered gas from being directly discharged and causing environmental pollution. At the same time, the liquid in the liquid seal space 230 can also isolate the electrolyte in the reaction space 220 from the air, reducing or preventing electrolyte deterioration.

[0047] In some optional embodiments, the liquid inlet 252 and the exhaust outlet 251 are hollow cylindrical nozzles that penetrate the transverse partition 250 and extend into the liquid-sealed space 230. Since the cylindrical wall of the hollow cylindrical nozzle can define a hollow cylindrical airflow channel, extending the hollow cylindrical nozzle into the liquid-sealed space 230 can guide the gas flowing through the exhaust outlet 251 upward, thereby improving the gas filtration efficiency and emission efficiency.

[0048] An outlet 231 may be provided on the top wall of the liquid-sealed space 230, connecting the liquid-sealed space 230 to allow the filtered gas to be discharged. In this embodiment, the top wall of the liquid-sealed space 230 is also the top wall of the reaction vessel 200. The gas flowing into the liquid-sealed space 230 eventually flows to the outlet 231 and is discharged to the external environment of the reaction vessel 200 through the outlet 231.

[0049] The liquid-sealed space 230 is used to collect and filter the gases generated by each electrolytic deoxygenation unit 100, and these gases are discharged uniformly through the outlet 231. When it is necessary to guide the gas through the gas guide pipe, it is only necessary to connect the gas guide pipe to the outlet 231. The structure is simple and easy to implement.

[0050] Since the reaction space 220 and the liquid seal space 230 are both integrated within the reaction vessel 200, by opening an opening in the transverse partition plate 250, the gas path and liquid path can be connected between the reaction space 220 and the liquid seal space 230, thereby realizing the filtration and recovery functions. Therefore, the electrolytic deoxygenation device 10 of the present invention has the advantages of simple structure and high degree of integration.

[0051] In some optional embodiments, there are multiple electrolytic deoxygenation units 100 and reaction spaces 220. Because there are multiple electrolytic deoxygenation units 100, each unit can consume oxygen through an electrochemical reaction under the action of an electrolysis voltage. When multiple electrolytic deoxygenation units 100 simultaneously carry out electrochemical reactions, each unit only needs to operate at a relatively small electrolysis voltage to achieve high deoxygenation efficiency. Therefore, the electrolytic deoxygenation device 10 of this embodiment improves deoxygenation efficiency while ensuring service life.

[0052] Figure 2 yes Figure 1 The diagram shows a schematic top view of the electrolytic deoxygenation device 10, which includes multiple reaction spaces 220 and multiple electrolytic deoxygenation units 100. The multiple reaction spaces 220 are not interconnected and are arranged sequentially in a horizontal direction.

[0053] Since the reaction spaces 220 are not interconnected, they are essentially set up independently and do not interfere with each other. Therefore, the gas generated in each reaction space 220 can only be discharged to the liquid-sealed space 230 through the exhaust port 251. This can prevent the gas generated in each reaction space 220 from entering other reaction spaces 220, which is beneficial to improving the gas emission efficiency of each reaction space 220 and avoiding excessive impact of gas on the various components of the electrolytic oxygen removal unit 100.

[0054] Since multiple reaction spaces 220 are arranged sequentially in the horizontal direction without obstructing each other, it can be ensured that each electrolytic deoxygenation unit 100 can smoothly contact the oxygen outside the reaction vessel 200. Each electrolytic deoxygenation unit 100 has an equal opportunity to contact the oxygen, and the entire electrolytic deoxygenation device 10 has high energy efficiency.

[0055] The reaction vessel 200 has at least one longitudinal partition plate 210, which extends longitudinally to divide a plurality of reaction spaces 220 arranged sequentially in the horizontal direction. The number of longitudinal partition plates 210 is set according to the number of reaction spaces 220, and is one less than the number of reaction spaces 220. For example, the plurality of longitudinal partition plates 210 can be in the form of plates or sheets, arranged parallel to each other, and the plate surface of each longitudinal partition plate 210 can be parallel to the vertical plane.

[0056] In some embodiments, the longitudinal partition plate 210 can be formed inside the reaction vessel 200 by injection molding, which simplifies the process, eliminates the complicated assembly process, and ensures the connectivity between adjacent reaction spaces 220.

[0057] In some optional embodiments, the electrolytic deoxygenation device 10 further includes a replenishment container 300 located above the reaction vessel 200, and its interior forming a storage space 310 connected to the liquid-sealed space 230 for replenishing the liquid-sealed space 230. For example, the replenishment container 300 can be a water tank with a supply port at its bottom and a corresponding inlet port 232 on the top wall of the liquid-sealed space 230. The supply port is higher than the inlet port 232, and the supply port and the inlet port 232 can be connected by a delivery pipe to guide the liquid flowing out of the supply port to the inlet port 232. A switching element 400 can be installed inside the delivery pipe for controlled opening and closing, thereby opening and closing the liquid path between the supply port and the inlet port 232.

[0058] In this embodiment, the electrolytic deoxygenation device 10 and the electrolytic deoxygenation unit 100 consume electrolyte during the electrochemical reaction. By temporarily storing a specific amount of liquid in the water tank, the replenishment requirements of the electrolytic deoxygenation unit 100 can be met within a certain range, reducing or avoiding the problem of the electrolytic deoxygenation unit 100 failing to work properly due to insufficient electrolyte. This is beneficial to improving the working performance of the electrolytic deoxygenation device 10.

[0059] The electrolytic deoxygenation unit 100 may generally include an anode plate 120 and a cathode plate 110.

[0060] The cathode plate 110 is used to consume oxygen through an electrochemical reaction under the action of an electrolysis voltage. The anode plate 120 is used to provide reactants (e.g., electrons) to the cathode plate 110 and generate gas through an electrochemical reaction under the action of an electrolysis voltage.

[0061] When an electric current is applied, for example, oxygen in the air can undergo a reduction reaction at the cathode plate 110, namely: O2 + 2H2O + 4e - →4OH - OH generated by cathode plate 110 - An oxidation reaction can occur at the anode plate 120, generating oxygen, i.e.: 4OH⁻- →O2 + 2H2O + 4e - .

[0062] The cathode plate 110 has a cathode terminal 111. The anode plate 120 has an anode terminal 121. The cathode terminals 111 and anode terminals 121 of adjacent electrolytic deoxygenation units 100 are connected, allowing multiple electrolytic deoxygenation units 100 to be connected in series. Since each electrolytic deoxygenation unit 100 can act as a voltage divider, this avoids increased wear rate due to excessive operating current, thus extending the service life of the electrochemical components.

[0063] In this embodiment, the electrochemical reaction of the electrolytic deoxygenation unit 100 consumes water. Therefore, it is only necessary to replenish water to the reaction space 220. The liquids in the water tank and the liquid seal space 230 can be water, respectively.

[0064] The above examples of electrochemical reactions of the anode plate 120 and the cathode plate 110 are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily change the type of electrochemical reaction or extend the structure of the electrolytic oxygen desorption device 10 applicable to other types of electrochemical reactions. All such changes and extensions should fall within the protection scope of this invention.

[0065] Figure 3 This is a schematic structural diagram of an electrolytic deoxygenation device 10 according to another embodiment of the present invention, and the diagram is a side view. In some embodiments, the reaction vessel 200 has an opening on the side wall of the reaction space 220, and the cathode plate 110 can be disposed at the opening and together with the reaction vessel 200 define the reaction space 220 for holding electrolyte. The anode plate 120 can be disposed in the reaction space 220 at intervals from the cathode plate 110.

[0066] In some alternative embodiments, at least a portion of the front wall of the liquid-sealed space 230 is recessed rearward to form a cable tray 280, in which cables can be arranged for connecting the electrolytic deoxygenation unit 100 to the power supply of the electrolytic deoxygenation device 10, so that the power supply provides electrolysis voltage to the electrolytic deoxygenation unit 100.

[0067] In some alternative embodiments, the cathode plate 110 may be disposed inside the reaction vessel 200. For example, the front wall of the reaction vessel 200 may have multiple holes to allow the cathode plate 110 to contact with external gas.

[0068] Figure 4This is a schematic structural diagram of a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 generally includes a cabinet 20 and an electrolytic deoxygenation device 10 as described in any of the above embodiments. The interior of the cabinet 20 defines a storage space. The electrolytic deoxygenation device 10 is installed in the cabinet 20 and is used to consume oxygen within the storage space. For example, the cathode plate may be in airflow communication with the storage space.

[0069] The refrigerator 1 in this embodiment is an electrical device with low-temperature storage function, which includes refrigerators in the narrow sense, as well as freezers, storage cabinets and other refrigeration and freezing devices.

[0070] In other embodiments, the electrolytic deoxygenation device 10 can also provide oxygen to the storage space to create a high-oxygen preservation atmosphere in the storage space. For example, the outlet of the electrolytic deoxygenation device can be connected to the airflow of the storage space.

[0071] The electrolytic deoxygenation device 10 and the refrigerator 1 having the present invention, since the interior of the reaction vessel 200 defines a liquid-sealed space 230 and a reaction space 220, the electrolytic deoxygenation unit 100 is assembled into the reaction space 220, and the gas generated when the electrolytic deoxygenation unit 100 performs an electrochemical reaction can flow through the liquid contained in the liquid-sealed space 230, so that specific substances in the gas dissolve in the liquid-sealed space 230. Therefore, the present invention provides an electrolytic deoxygenation device 10 with a filtration function, which is beneficial to reduce or avoid environmental pollution caused by gas emissions.

[0072] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
