Further, the electrolytic oxygen removal device 40 can further include an encapsulation shell 100, a cathode composite plate 200, an anode plate 300, and an electrolyte module 400.

[0036] The packaging shell 100 has electrolytic cavities 110 and liquid supplement cavities 130 arranged at intervals, and the wall surface of the electrolytic cavities 110 away from the liquid supplement cavities 130 has openings 140.

[0037] The cathode composite plate 200 is arranged in the electrolytic cavities 110 and located at the openings 140, and the cathode composite plate 200 can allow air flowing therethrough to enter the electrolytic cavities 110 to consume oxygen in the air through an electrochemical reaction.

[0038] The anode plate 300 is arranged in the electrolytic cavities 110, and the anode plate 300 can provide reactants (such as electrons) to the cathode composite plate 200 through an electrochemical reaction and generate oxygen.

[0039] The electrolyte module 400 is arranged in the electrolytic cavities 110 between the cathode composite plate 200 and the anode plate 300, and has electrolyte adsorbed therein for conducting electricity, and the electrolyte module 400 can further include a first adsorbent 410 having a main plate 412 and a connecting piece 414 connected to the main plate 412 and the liquid supplement cavities 130, and the connecting piece 414 is configured to absorb electrolyte solvent in the liquid supplement cavities 130 and conduct to the main plate 412 to maintain the saturation of the electrolyte module 400.

[0040] In the embodiment, the packaging shell 100 is opened to form the openings 140 on the wall surface of the electrolytic cavities 110 away from the liquid supplement cavities 130, and the cathode composite plate 200 is arranged at the openings 140, that is, the cathode composite plate 200 can serve as a side wall of the electrolytic cavities 110, air in the storage space of the refrigerator 1 can flow through the cathode composite plate 200, the cathode composite plate 200 has a waterproof and air-permeable function, can allow air to enter the electrolytic cavities 110, and the cathode composite plate 200 can be loaded with a negative electrode of an external power supply, and oxygen in the air can be reduced at the cathode composite plate 200 to generate negative ions, that is: O2+2H2O+4e - →4OH - .

[0041] The anode plate 300 can be arranged in the electrolytic cavities 110 at intervals with the cathode composite plate 200 and loaded with a positive electrode of an external power supply, and the negative ions generated at the cathode composite plate 200 flow to the anode plate 300 under the action of an electric field and are oxidized at the anode plate 300 to generate oxygen, that is: 4OH - →O2+2H2O+4e - .

[0042] The electrolyte module 400 is arranged in the electrolytic cavities 110 between the cathode composite plate 200 and the anode plate 300, and can be used to conduct the cathode composite plate 200 and the anode plate 300 to realize ion exchange, for example, the negative ions generated at the cathode composite plate 200 can flow to the anode plate 300 under the action of an electric field.

[0043] The electrolyte can be composed of an electrolyte and an electrolyte solvent, wherein the electrolyte can be NaOH, etc., and the electrolyte solvent can be pure water, and finally can be configured into a 0.1-8 mol / L NaOH electrolyte solution (the concentration can be adjusted according to actual conditions).

[0044] Before use, the electrolyte module 400 can pre-adsorb sufficient electrolyte, the first adsorbent body 410 of the electrolyte module 400 has a main plate 412 and a connecting piece 414, the main plate 412 and the connecting plate can be integrally formed, and both have a certain liquid absorption capacity, the electrolyte solvent is pre-filled in the liquid supplementing cavity 130, and the connecting piece 414 is immersed in the electrolyte solvent in the liquid supplementing cavity 130. In this way, the electrolyte solvent in the liquid supplementing cavity 130 can be continuously supplied to the main plate 412 through the connecting piece 414, so that the main plate 412 is in a saturated state, and the electrolyte module 400 has the function of electrically connecting the cathode composite plate 200 and the anode plate 300.

[0045] As described in the background section, the electrolysis oxygen removal device in the prior art needs to be provided with a liquid supplementing system (a liquid supplementing switch, a liquid level meter, etc.), which increases the additional burden of the electrolysis oxygen removal device which is itself space-limited, and has a complex structure, which is not conducive to installation, maintenance, etc.

[0046] In order to overcome the defects of the prior art, the first adsorbent body 410 of the electrolysis oxygen removal device 40 of the embodiment has a certain water absorption capacity, the connecting piece 414 of the first adsorbent body 410 connects the main plate 412 and the electrolyte solvent in the liquid supplementing cavity 130, and before the first adsorbent body 410 reaches a saturated state, the electrolyte solvent is continuously absorbed from the liquid supplementing cavity 130 until the electrolyte module 400 reaches a saturation degree. In the working process, the electrolyte solvent in the electrolyte module 400 is continuously consumed, and then it is spontaneously supplemented from the electrolyte solvent in the liquid supplementing cavity 130. That is, the electrolyte module 400 of the embodiment can realize automatic liquid supplementing, without the need to set a complex liquid supplementing system, thereby simplifying the structure of the electrolysis oxygen removal device 40 and reducing the difficulty and cost of installation and maintenance.

[0047] In addition, the cathode composite plate 200 is a wall surface of the electrolysis cavity 110, and once the cathode composite plate 200 is pierced by an external object, there is a risk of electrolyte leakage. In the embodiment, a large amount of liquid electrolyte solvent is contained in the liquid supplementing cavity 130, and the electrolyte module 400 has at most a small amount of electrolyte adsorbed to maintain its electrical conductivity. Even if the cathode composite plate 200 is broken, it will not cause a large amount of electrolyte leakage, so the waste tank for collecting the leaked electrolyte can be cancelled, thereby further simplifying the structure of the electrolysis oxygen removal device 40 and improving the reliability of the electrolysis oxygen removal device 40.

[0048] Referring to Figure 4In some embodiments, the electrolyte module 400 can further include two second adsorbents 420, each of which is arranged in the electrolytic cavity 110 and attached to two sides of the main plate 412 respectively, and in contact with the cathode composite plate 200 and the anode plate 300 respectively, so as to absorb the electrolyte in the main plate 412 and electrically connect the cathode composite plate 200 and the anode plate 300.

[0049] That is, the structure in the electrolytic cavity 110 of the embodiment is that the cathode composite plate 200, the second adsorbent 420, the main plate 412, the second adsorbent 420 and the anode plate 300 are sequentially arranged in the opening 140 of the packaging shell 100 towards the inside, and the adjacent two components are tightly attached, so that the electrolyte adsorbed by the main plate 412 can diffuse to the second adsorbents 420 located on its two sides, and the two second adsorbents 420 are attached to the cathode composite plate 200 and the anode plate 300 respectively, so that the cathode composite plate 200 and the anode plate 300 are electrically connected, and ion exchange can be achieved.

[0050] In some specific embodiments, the first adsorbent 410 can also be configured as a hard plate, such as a non-woven cloth pressing plate, a fiber plate, etc., to provide strength support for the electrolyte module 400, and the second adsorbent 420 can also be configured as a soft and elastic water-absorbing plate, such as a polyvinyl alcohol sponge, etc., so as to not only absorb more electrolyte and improve the conductivity of the electrolyte module 400, but also tightly attach to the cathode composite plate 200 or the anode plate 300 to prevent open circuit.

[0051] Referring to Figure 5 and Figure 6 , Figure 6 is a longitudinal sectional view of the packaging shell 100 in the electrolytic deoxidizing device 40 according to an embodiment of the present application. In some embodiments, a preset space 160 is formed between the bottom of the electrolyte module 400 and the bottom wall of the electrolytic cavity 110, so as to collect the electrolyte flowing out of the electrolyte module 400, and the first adsorbent 410 further includes an absorption portion 416 formed at the bottom of the main plate 412, which extends into the preset space 160 and absorbs the electrolyte, so as to maintain the saturation of the electrolyte module 400.

[0052] Specifically, the two sides of the bottom wall of the electrolytic cavity 110 have bosses 120, and the two ends of the bottom of the electrolyte module 400 are arranged on the two bosses 120 respectively, so as to form the preset space 160 in the middle below, and the two bosses 120 can also support the electrolyte module 400, so that it is stably arranged in the electrolytic cavity 110. Of course, those skilled in the art can also use other fixing means (fasteners, etc.) to realize that the electrolyte module 400 is suspended in the electrolytic cavity 110, and the bottom forms the preset space 160, which is not listed one by one here.

[0053] Before assembling the electrolysis oxygen-removing device 40, the electrolyte module 400 can be pre-absorbed with enough electrolyte. If the electrolyte module 400 is in a supersaturated state, the electrolyte flows into the preset space 160 at the bottom of the electrolyte module 400 under the action of gravity, and the excess electrolyte is collected.

[0054] As the electrochemical reaction continuously proceeds, the saturation of the electrolyte module 400 decreases, the absorption part 416 of the first adsorbent 410 extends into the preset space 160, and the collected excess electrolyte is supplied to the main plate 412, thereby maintaining the saturation of the electrolyte module 400. In this way, not only can the collected electrolyte be fully utilized to avoid waste, but also the long-term residue of excess electrolyte at the bottom of the electrolysis cavity 110 can be prevented from volatilization and deterioration.

[0055] Referring to Figure 3 and Figure 4 In some embodiments, the electrolysis cavity 110 and the liquid supplement cavity 130 are both upwardly open, and the electrolysis oxygen-removing device 40 can further include a cover 500 arranged on the packaging shell 100 to cover the electrolysis cavity 110 and the liquid supplement cavity 130.

[0056] Referring to Figure 4 Since the main plate 412 of the first adsorbent 410 is located in the electrolysis cavity 110, and the connecting piece 414 is connected between the main plate 412 and the liquid supplement cavity 130, the connecting piece 414 needs to cross the partition plate 150 between the electrolysis cavity 110 and the liquid supplement cavity 130. When the cover 500 covers the electrolysis cavity 110 and the liquid supplement cavity 130, the connecting piece 414 can also be pressed on the partition plate 150 to fix the first adsorbent 410.

[0057] The cover 500 can be provided with an exhaust port 510 for discharging oxygen. The exhaust port 510 can also be arranged close to the anode plate 300, so that the oxygen generated by the anode plate 300 is more smoothly discharged, thereby promoting the electrochemical reaction to proceed in the positive direction and improving the oxygen-removing efficiency.

[0058] The cover 500 can also be provided with a first liquid injection port 512 for injecting electrolyte into the electrolysis cavity 110, so as to pre-absorb enough electrolyte for the electrolyte module 400.

[0059] The packaging shell 100 can also be provided with a second liquid injection port (not shown in the figure) for injecting electrolyte solvent into the liquid supplement cavity 130, so as to periodically supplement the electrolyte solvent to the liquid supplement cavity 130. Since only the electrolyte solvent in the electrolyte is consumed in the subsequent work of the electrolysis oxygen-removing device 40, only the electrolyte solvent needs to be added to the liquid supplement cavity 130 through the second liquid injection port after a period of use.

[0060] The first liquid injection port 512 and the second liquid injection port can also be respectively provided with liquid injection plugs 520 to block the first liquid injection port 512 and the second liquid injection port.

[0061] Referring to Figure 3 In some embodiments, the cathode composite plate 200 can be sequentially provided with the catalytic layer 210, the first waterproof and air-permeable layer 220, the conductive layer 230 and the second waterproof and air-permeable layer 240 from inside to outside, which can be understood as from the inside of the encapsulation shell 100 to the direction of the opening 140. The catalytic layer 210 can adopt a noble metal or rare metal catalyst, such as metal platinum, metal gold, metal silver, metal manganese or metal rubidium, etc. The first waterproof and air-permeable layer 220 and the second waterproof and air-permeable layer 240 can be waterproof and air-permeable films, so that the electrolyte cannot seep out of the liquid storage cavity, and air can enter the liquid storage cavity through the first waterproof and air-permeable layer 220 and the second waterproof and air-permeable layer 240. The conductive layer 230 can be made of a corrosion-resistant metal current collector, such as metal nickel, metal titanium, etc., so as to have better conductivity, corrosion resistance and support strength.

[0062] The anode plate 300 can be made of a material with strong corrosion resistance and reducibility, such as metal foam nickel, nickel mesh, etc.

[0063] At this point, those skilled in the art should recognize that, although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be directly determined or deduced according to the disclosure of the present application without departing from the spirit and scope of the present application, which conform to the principles of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variations or modifications.
