[0002] An electrolytic oxygen desiccant consumes oxygen in the working environment through an electrochemical reaction under the action of an electrolytic voltage.

[0003] The inventors recognized that, under normal circumstances, to increase the rate at which an electrolytic oxygen desorption device consumes oxygen, it is necessary to increase the electrolysis voltage or increase the current flowing through the electrochemical elements of the electrolytic oxygen desorption device. This would lead to an increased wear rate of the electrochemical elements and a shortened lifespan of the electrochemical elements. Summary of the Invention

[0005] A further objective of this invention is to improve the deoxygenation efficiency of the electrolytic deoxygenation device while ensuring its service life.

[0006] Another further objective of the present invention is to maintain a consistent lifespan for multiple electrolytic deoxygenation units.

[0007] Another further objective of the present invention is to simplify the liquid replenishment process of the electrolytic deoxygenation device.

[0008] Another further object of the present invention is to enable the electrolytic deoxygenation device to treat the emitted gas in order to prevent environmental pollution.

[0009] In particular, according to one aspect of the present invention, an electrolytic deoxygenation device is provided, comprising: a reaction vessel having internally defined plurality of reaction spaces for holding electrolyte; the plurality of reaction spaces being interconnected to form a through channel for the flow of electrolyte; and a plurality of electrolytic deoxygenation units, each corresponding to one of the reaction spaces, wherein each electrolytic deoxygenation unit is respectively assembled to a reaction space for consuming oxygen outside the reaction vessel through an electrochemical reaction under the action of an electrolysis voltage.

[0010] Optionally, multiple reaction spaces are arranged sequentially along the horizontal direction, and adjacent reaction spaces are interconnected to form a through channel.

[0011] Optionally, the reaction vessel has at least one longitudinal partition plate extending longitudinally to separate multiple reaction spaces arranged sequentially in the horizontal direction; and the longitudinal partition plate has a communication port so that adjacent reaction spaces can communicate with each other.

[0012] Optionally, the interior of the reaction vessel also defines a processing space, located above the multiple reaction spaces and connected to each of the reaction spaces, so as to allow the gas generated during the electrochemical reaction of each electrolytic deoxygenation unit to flow into it; and the top wall of the processing space is provided with an outlet to allow the gas flowing into the processing space to be discharged.

[0013] Optionally, the reaction vessel has a transverse partition plate that extends laterally to separate the processing space and the reaction space arranged vertically; and the transverse partition plate has multiple exhaust holes that are connected to the reaction space one by one.

[0014] Optionally, a liquid replenishment hole is also provided on the transverse partition plate, which is connected to any reaction space to allow liquid flowing through the processing space to flow into the reaction space.

[0015] Optionally, the liquid replenishment hole and the vent hole are light holes that penetrate through the thickness direction of the transverse partition plate; and the hole wall of the liquid replenishment hole extends upward, and an upper annular flange that penetrates the liquid replenishment hole and the processing space is formed on the upper surface of the transverse partition plate.

[0016] 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 processing space for replenishing the processing space.

[0017] 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.

[0018] 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.

[0019] The electrolytic deoxygenation device and the refrigerator having the present invention have multiple electrolytic deoxygenation units. Each electrolytic deoxygenation unit can consume oxygen by performing an electrochemical reaction under the action of an electrolysis voltage. When multiple electrolytic deoxygenation units perform an electrochemical reaction simultaneously, each electrolytic deoxygenation unit only needs to operate under a smaller electrolysis voltage to obtain a higher deoxygenation efficiency. Therefore, the electrolytic deoxygenation device of the present invention improves the deoxygenation efficiency while ensuring its service life.

[0020] Furthermore, in the electrolytic deoxygenation device and refrigerator of the present invention, each electrolytic deoxygenation unit is respectively disposed in a reaction space, and the reaction spaces are interconnected to form a through channel for the flow of electrolyte. The electrolyte can flow freely in multiple reaction spaces, and the electrolyte in each reaction space remains basically uniform. This is beneficial to ensure that the electrochemical reaction rate of each electrolytic deoxygenation unit is consistent, thereby ensuring that the service life of multiple electrolytic deoxygenation units is consistent.

[0021] Furthermore, the electrolytic deoxygenation device and the refrigerator having the present invention, by arranging multiple reaction spaces in a continuous manner and providing a processing space above the multiple reaction spaces, and by allowing the liquid flowing through the processing space to flow into any reaction space through a replenishment hole, the liquid flowing into any reaction space can be evenly distributed to other reaction spaces, thereby completing the replenishment, which helps to simplify the replenishment process of the electrolytic deoxygenation device.

[0022] Furthermore, in the electrolytic deoxygenation device and refrigerator of the present invention, since the wall of the replenishment hole extends upward to form an upper annular flange, which is set higher than the exhaust hole, when replenishing the reaction space with liquid using the processing space, the liquid level in the processing space needs to be higher than the upper annular flange. The liquid in the processing space can act as a liquid seal for the exhaust hole. The gas flowing out of the exhaust hole needs to flow through the liquid in the processing space before flowing out of the processing space. When the gas flows through the liquid in the processing space, the liquid it carries can dissolve in the processing space, which can reduce or avoid environmental pollution caused by gas emissions.

[0023] 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

[0024] The following sections will describe some specific embodiments of the invention in detail by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0028] Figure 4This is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. Detailed Implementation

[0029] 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.

[0030] The electrolytic deoxygenation apparatus 10 generally includes a reaction vessel 200 and multiple electrolytic deoxygenation units 100.

[0031] The reaction vessel 200 internally defines multiple reaction spaces 220 for holding electrolyte. These multiple reaction spaces 220 are interconnected to form a through channel 221 for electrolyte flow. In this embodiment, the reaction spaces 220 are directly or indirectly connected to each other, thus forming the through channel 221 for electrolyte flow, and the electrolyte within each reaction space 220 is homogeneous.

[0032] Multiple electrolytic deoxygenation units 100 are arranged one-to-one with the reaction spaces 220, and each electrolytic deoxygenation unit 100 is assembled into a reaction space 220 to consume oxygen outside the reaction vessel 200 through electrochemical reaction under the action of electrolysis voltage. In this embodiment, each electrolytic deoxygenation unit 100 can independently carry out electrochemical reaction, and when multiple electrolytic deoxygenation units 100 carry out electrochemical reaction simultaneously, the deoxygenation efficiency of the electrolytic deoxygenation device 10 is accumulated.

[0033] The electrolytic deoxygenation device 10 and the refrigerator 1 having the present invention have multiple electrolytic deoxygenation units 100. Each electrolytic deoxygenation unit 100 can consume oxygen by performing an electrochemical reaction under the action of an electrolysis voltage. When multiple electrolytic deoxygenation units 100 perform an electrochemical reaction simultaneously, each electrolytic deoxygenation unit 100 only needs to operate under a smaller electrolysis voltage to obtain a higher deoxygenation efficiency. Therefore, the electrolytic deoxygenation device 10 of the present invention improves the deoxygenation efficiency, ensures the service life, and has high safety.

[0034] Figure 2 yes Figure 1 The diagram shows a schematic top view of the electrolytic deoxygenation device 10, illustrating the reaction space 220 and the electrolytic deoxygenation unit 100. Since each electrolytic deoxygenation unit 100 is disposed in a reaction space 220, and the reaction spaces 220 are interconnected, a through channel 221 for the flow of electrolyte is formed (e.g., ...). Figure 2(As shown by the dashed line), the electrolyte can flow freely within multiple reaction spaces 220, and the electrolyte in each reaction space 220 remains essentially uniform. This helps ensure that the electrochemical reaction rate of each electrolytic deoxygenation unit 100 is consistent, thereby ensuring that the service life of multiple electrolytic deoxygenation units 100 is consistent. When all electrolytic deoxygenation units have aged, they can be replaced uniformly, which helps reduce maintenance costs.

[0035] In some optional embodiments, multiple reaction spaces 220 are arranged sequentially in a horizontal direction, and adjacent reaction spaces 220 are interconnected to form a through channel 221. In this embodiment, by making adjacent reaction spaces 220 directly connected, reaction spaces 220 that are not directly connected can be indirectly connected, thereby enabling multiple reaction spaces 220 to be connected to form a through channel 221.

[0036] By arranging multiple reaction spaces 220 sequentially along the horizontal direction, it can be ensured that the height of each reaction space 220 is basically the same. Since adjacent reaction spaces 220 are interconnected, each reaction space 220 forms a communicating vessel through the connection. Based on this communicating vessel structure, the electrolyte in each reaction space 220 can be evenly distributed without the need for external force interference, and the electrolyte level and concentration are basically the same.

[0037] 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, and each electrolytic deoxygenation unit 100 has an equal opportunity to contact the oxygen.

[0038] In some optional embodiments, the reaction vessel 200 has at least one longitudinal partition plate 210, each extending longitudinally to divide a plurality of reaction spaces 220 arranged sequentially in the horizontal direction. The number of longitudinal partition plates 210 is determined 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 may be in the form of a plate or a sheet, arranged parallel to each other, and the plate surface of each longitudinal partition plate 210 may be parallel to a vertical plane.

[0039] A connecting port 211 is provided on the longitudinal partition plate 210, allowing adjacent reaction spaces 220 to communicate with each other. Electrolyte in one reaction space 220 can flow into other reaction spaces 220 through the connecting port 211. The electrolytic deoxygenation device 10 of this embodiment, by providing the connecting port 211 on the longitudinal partition plate 210, can connect all reaction spaces 220, possessing the advantage of a compact structure. The connecting port 211 can be located in the bottom section of the longitudinal partition plate 210.

[0040] In other embodiments, the connection port 211 may not be provided on the longitudinal partition plate 210. For example, a gap may be formed between the longitudinal partition plate 210 and the bottom wall of the reaction space 220 to form the connection port 211.

[0041] 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.

[0042] In some optional embodiments, the interior of the reaction vessel 200 further defines a processing space 230, located above and connected to each of the plurality of reaction spaces 220, to allow gases generated during the electrochemical reaction of each electrolytic deoxygenation unit 100 to flow into it. That is, in this embodiment, the upper space of the reaction vessel 200 is the processing space 230, and the lower space is the reaction space 220.

[0043] The gases generated during the electrochemical reaction in the electrolytic deoxygenation unit 100 are formed in their respective reaction spaces 220. Since the processing space 230 is connected to each reaction space 220, the gases generated by each electrolytic deoxygenation unit 100 can flow into the processing space 230.

[0044] An outlet 231 is provided on the top wall of the processing space 230 to allow the gas flowing into the processing space 230 to be discharged. In this embodiment, the top wall of the processing space 230 is also the top wall of the reaction vessel 200. The gas flowing into the processing space 230 eventually flows to the outlet 231 and is discharged to the external environment of the reaction vessel 200 through the outlet 231.

[0045] The gas generated by each electrolytic deoxygenation unit 100 is collected in the processing space 230 and discharged uniformly through the outlet 231. When it is necessary to guide the gas through the gas guide tube, it is only necessary to connect the gas guide tube to the outlet 231. The structure is simple and easy to implement.

[0046] In some optional embodiments, the reaction vessel 200 has a transverse partition 250 extending laterally to separate the vertically arranged processing space 230 and reaction space 220. In this embodiment, there is only one transverse partition 250. For example, the transverse partition 250 can be flat or sheet-like, and its surface can be parallel to the horizontal plane.

[0047] The transverse partition plate 250 has multiple exhaust holes 251, each communicating with the reaction space 220. In this embodiment, the electrolytic deoxygenation device 10 connects the reaction space 220 and the processing space 230 by providing exhaust holes 251 on the transverse partition plate 250, resulting in a compact structure. Since both the processing space 230 and the reaction space 220 are integrated within the reaction vessel 200 and separated by a transverse partition plate 250 with exhaust holes 251, both the gas guiding structure and airtightness are ensured.

[0048] The exhaust rate of the exhaust port 251 is greater than the maximum gas generation rate of the electrolytic deoxygenation unit 100, so as to prevent the impact of the large gas pressure formed in the reaction space 220 on the various components of the electrolytic deoxygenation unit 100.

[0049] 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 reactions.

[0050] In some further embodiments, the transverse partition 250 is also provided with a liquid replenishment hole 252 to allow liquid flowing through the processing space 230 to flow into the reaction space 220. That is, the processing space 230 in this embodiment can not only serve as a gas collection chamber but also as a liquid supply chamber for supplying liquid to the reaction space 220. Liquid from outside the processing space 230 can flow into the reaction space 220 through the liquid replenishment hole 252 after passing through the processing space 230.

[0051] There is one replenishment hole 252, which can connect to any reaction space 220. By connecting multiple reaction spaces 220 and setting a processing space 230 above the multiple reaction spaces 220, and allowing the liquid flowing through the processing space 230 to flow into any reaction space 220 through the replenishment hole 252, the liquid flowing into any reaction space 220 can be evenly distributed to other reaction spaces 220, thereby completing the replenishment. This simplifies the replenishment process of the electrolytic oxygenation device 10.

[0052] In some embodiments, the number of replenishment holes 252 can also be set to multiple according to actual needs, which can improve replenishment efficiency and enable the electrolyte in each reaction space 220 to achieve uniformity at a faster speed.

[0053] In some optional embodiments, the liquid replenishment hole 252 and the vent hole 251 are light holes that penetrate the thickness direction of the transverse partition plate 250. For example, the liquid replenishment hole 252 can connect to the reaction space 220 located at the end of the reaction vessel 200. The vent hole 251 can be located close to the anode plate 120 of the electrolytic deoxygenation unit 100 and away from the cathode plate 110 of the electrolytic deoxygenation unit 100, thereby ensuring the gas discharge efficiency of the reaction space 220.

[0054] The wall of the replenishment hole 252 extends upward, and an upper annular flange 260 is formed on the upper surface of the transverse partition plate 250, connecting the replenishment hole 252 and the processing space 230. That is, the upper annular flange 260 is a hollow cylinder, and its wall encloses a hollow channel communicating with the replenishment hole 252. The liquid in the processing space 230 needs to flow through the hollow channel of the upper annular flange 260, then through the replenishment hole 252, and finally into the reaction space 220.

[0055] Since the wall of the replenishment hole 252 extends upward to form an upper annular flange 260, which is set higher than the vent hole 251, when replenishing the reaction space 220 with liquid using the processing space 230, the liquid level in the processing space 230 needs to be set higher than the upper annular flange 260. The liquid in the processing space 230 can act as a liquid seal for the vent hole 251. The gas flowing out of the vent hole 251 needs to flow through the liquid in the processing space 230 before flowing out of the processing space 230. When the gas flows through the liquid in the processing space 230, the liquid it carries (such as electrolytes) can dissolve in the processing space 230. This can reduce or avoid environmental pollution caused by gas emissions.

[0056] Meanwhile, the substances dissolved in the processing space 230 can return to the reaction space 220 through the replenishment hole 252 for recycling. Therefore, the electrolytic deoxygenation device 10 of this embodiment has a filtration and recovery function, which improves resource utilization efficiency and reduces or avoids electrolyte waste caused by direct gas emission.

[0057] The liquid in the processing space 230 can also isolate the electrolyte in the reaction space 220 from the air, reducing or preventing electrolyte deterioration.

[0058] In some alternative embodiments, the wall of the vent 251 may also extend upward, and another upper annular flange 260, which can be named the second upper annular flange 260, is formed on the upper surface of the transverse partition plate 250, penetrating the vent 251 and the processing space 230. The upper annular flange 260, which penetrates the replenishment hole 252 and the processing space 230, can be named the first upper annular flange 260. The first upper annular flange 260 is higher than the second upper annular flange 260 to ensure that the liquid in the processing space 230 can liquid seal the vent 251.

[0059] Since the interior of the second upper annular flange 260 defines an airflow channel extending from bottom to top, it can guide the airflow passing through it upward, which is beneficial to improving the gas emission efficiency.

[0060] 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 processing space 230 for replenishing the processing space 230 with liquid. 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 processing 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 switching the liquid path between the supply port and the inlet port 232.

[0061] 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.

[0062] The electrolytic deoxygenation unit 100 may generally include an anode plate 120 and a cathode plate 110.

[0063] 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.

[0064] 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 - .

[0065] 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.

[0066] 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 processing space 230 can be water, respectively.

[0067] 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.

[0068] 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.

[0069] In some alternative embodiments, at least a portion of the front wall of the processing space 230 is recessed rearward to form a cable tray 280, in which cables can be arranged to connect 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.

[0070] 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.

[0071] Figure 4 This 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.

[0072] 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.

[0073] 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.

[0074] The electrolytic deoxygenation device 10 and the refrigerator 1 having the present invention have multiple electrolytic deoxygenation units 100. Each electrolytic deoxygenation unit 100 can consume oxygen by performing an electrochemical reaction under the action of an electrolysis voltage. When multiple electrolytic deoxygenation units 100 perform an electrochemical reaction simultaneously, each electrolytic deoxygenation unit 100 only needs to operate under a smaller electrolysis voltage to obtain a higher deoxygenation efficiency. Therefore, the electrolytic deoxygenation device 10 of the present invention improves the deoxygenation efficiency while ensuring service life and having high safety.

[0075] 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.
