The housing 110 has a lateral opening 114 formed therein facing the interior of the first storage compartment 210. In this embodiment, the lateral opening 114 is located at the front side of the housing 110.
Cathode plates 120 are disposed at lateral openings 114 to define, together with housing 110, a reservoir for holding an electrolyte for consuming oxygen in first storage compartment 210 by electrochemical reaction. Cathode plate 120 is in airflow communication with the interior space of first storage compartment 210. For example, oxygen in the air may undergo a reduction reaction at cathode plate 120, i.e.: o is 2 +2H 2 O+4e-→4OH-。
An anode plate 140 is disposed within the reservoir chamber for providing reactants (e.g., electrons) to the cathode plate 120 via an electrochemical reaction and generating oxygen. The anode plate 140 may be disposed in the reservoir chamber spaced apart from the cathode plate 120, i.e., the anode plate 140 may be disposedOn the side of the cathode plate 120 opposite to the first storage compartment. OH "produced by the cathode plate 120 may undergo an oxidation reaction at the anode plate 140 and generate oxygen, i.e.: 4OH- → O 2 +2H 2 O+4e-。
The liquid storage cavity of the electrolytic oxygen removal device 100 can be filled with alkaline electrolyte, such as 0.1-8 mol/L NaOH, and the concentration of the alkaline electrolyte can be adjusted according to actual needs.
The air outlet 112 is disposed on the housing 110 and is communicated with the liquid storage cavity. In this embodiment, the vent 112 may be located at a top section of the housing 110 and configured to be higher than a highest level of the electrolyte in the reservoir chamber. For example, the housing 110 may have a rectangular parallelepiped flat box shape and be arranged extending in the vertical direction. The exhaust port 112 may be located on a top wall of the housing 110. The vertical direction is the height direction of the refrigerator.
Since the vent 112 of the electrolytic deoxygenator device 100 is located at the top section of the housing 110 and is configured to be higher than the highest level of electrolyte in the reservoir, leakage of electrolyte from the electrolytic deoxygenator device 100 of the refrigerator 10 during venting can be reduced or avoided.
In some optional embodiments, the vent 112 may also serve as a fluid infusion port for the electrolyte, and when the electrolyte is insufficient, the electrolyte may be injected into the reservoir at the vent 112, which may achieve the function reuse of the vent 112, and is beneficial to simplifying the structure of the electrolytic oxygen removal device 100.

Specifically, the separator 130 is formed with a plurality of protrusions 132 on a side facing the anode plate 140, the protrusions 132 abut against the anode plate 140, and the cathode plate 120 abuts against a side of the separator 130 facing away from the protrusions 132 to form a predetermined gap between the cathode plate 120 and the anode plate 140, thereby separating the cathode plate 120 from the anode plate 140.
A fixing assembly 150 may be provided at the outer side of cathode plate 120, configured to fix cathode plate 120 at lateral opening 114 of case 110. Specifically, the fixing assembly 150 may further include a metal bezel 152 and a support 154.
Fig. 8 is a schematic view of the support 154 in the electrolytic oxygen-removing device 100 shown in fig. 7, and fig. 9 is a partially enlarged view at B in fig. 8. The metal frame 152 abuts against the outside of the cathode plate 120, and the metal frame 152 is formed with a surrounding portion 152a protruding outward. The supporting member 154 is disposed at the outer side of the metal frame 152, and has an outer ring 1542 and an inner ring 1544 located inside the outer ring 1542, the outer ring 1542 is fixedly connected to the housing 110, an insertion groove 1544a is formed at the inner side of the inner ring 1544, and the surrounding portion 152a extends into the insertion groove 1544a to fix the metal frame 152 and the cathode plate 120 at the opening. In this embodiment, the metal frame 152 is in direct contact with the cathode plate 120, the metal frame 152 may function to press the cathode plate 120, and a cathode power supply terminal 152b of the cathode plate 120 may be further provided on the metal frame 152 to be connected to an external power source.
The surrounding portion 152a is formed on the metal frame 152 and extends outward to be inserted into the inner ring 1544 insertion groove 1544a of the supporting member 154, so as to position the metal frame 152. Since outer ring 1542 of support member 154 is fixedly connected to housing 110, when standing portion 152a of metal frame 152 is inserted into insertion groove 1544a of support member 154, metal frame 152 can be fixed and positioned by support member 154, so that metal frame 152 presses cathode plate 120.
In some embodiments, a reinforcing rib 1546 is further formed between the outer ring 1542 and the inner ring 1544 of the supporting member 154 and inside the inner ring 1544 for fixedly connecting the outer ring 1542 and the inner ring 1544 of the supporting member 154 and shaping the outer ring 1542 and the inner ring 1544 of the supporting member 154 to prevent them from being deformed by an external force.
The material of the anode plate 140 may be nickel, but is not limited thereto.
The cathode plate 120 may be sequentially provided with a catalyst layer, a first waterproof breathable layer, a current collecting layer, and a second waterproof breathable layer from the inside to the outside. Wherein the directional terms such as "outer" and "inner" are relative to the actual usage of housing 110, and relative to other structures of cathode plate 120, the catalytic layer may be located at the innermost side of cathode plate 120 so as to be in contact with the electrolyte in the liquid storage chamber.
The catalytic layer may be a metal catalyst, wherein the metal may be a noble metal or a rare metal, and may be selected from the group consisting of platinum, gold, silver, manganese, and rubidium, for example. The metal catalyst particles may be attached to acetylene black particles. First waterproof ventilative layer and the waterproof ventilative layer of second can be waterproof ventilated membrane to make electrolyte can't ooze from the stock solution chamber, thereby the air can see through first waterproof ventilative layer and the waterproof ventilative layer of second and catalytic layer contact. The current collecting layer can be made into a corrosion-resistant metal current collecting net, such as metal nickel, metal titanium and the like, so that the current collecting layer not only has better conductivity, corrosion resistance and supporting strength. And because cathode plate 120 itself has certain intensity, can satisfy the sealing strength demand of stock solution chamber completely, cathode plate 120 adopts two-layer waterproof ventilative layer also can prevent effectively because the leakage that electrolyte corrosion arouses in addition.
